Keir Starmer’s premiership is hanging by a thread this weekend as new details about Peter Mandelson’s friendship with the convicted paedophile Jeffrey Epstein continue to drip into the public consciousness.

When the prime minister sacked Mandelson as the UK’s ambassador to Washington over his Epstein ties in September, he must have hoped the scandal was dealt with. The events of the past week show how wrong he was.

The latest chapter in the saga was triggered by the US Department of Justice publishing more than three million documents on the late sex offender and his connections to the rich and powerful.

The files revealed that Mandelson was even more entwined with the disgraced financier than previously assumed – putting Starmer’s judgement in appointing him to the plum diplomatic role into sharp focus.

Amid mounting anger from the public and his own MPs, the prime minister ended up apologising on Thursday for ever believing Mandelson’s “lies”.

Here’s a breakdown of how we got to this point – and what might happen next.

Mandelson has been in Labour circles for decades, often referred to as the “Prince of Darkness” because of his ruthless nature, capacity for scandals and love of political intrigue.

He worked as the director of communications to then-party leader Neil Kinnock in the 1980s before being elected as the Labour MP for Hartlepool in 1992.

A key architect of the New Labour project, he helped Tony Blair win the party leadership in 1994 and ran Labour’s successful general election campaign in 1997.

Blair rewarded Mandelson with the post of minister without portfolio, a roving commission which gave him enormous power over the government machine.

However, the personal frailties – and the attraction to money – which would later bring about his downfall led to his resignation after barely a year when he failed to declare a loan from a cabinet colleague whose business dealings Mandelson’s own department was investigating.

After a year on the backbenches licking his wounds, Blair brought him back into the cabinet as Northern Ireland secretary the following year, at the time a key role as the peace process faltered.

But once again, barely a year later, Mandelson was forced to resign, this time for lying about his role in brokering a British passport for a wealthy donor to the Millennium Dome project.

After famously declaring he was “a fighter, not a quitter” when retaining his Hartlepool seat in 2001, Mandelson stood down as an MP in 2004 to become a European trade commissioner, a post he held until he made another dramatic political comeback in 2008.

Gordon Brown, who had succeeded Blair the previous year, stunned Westminster by making Mandelson – his New Labour nemesis – a life peer and appointing him business secretary and de facto deputy prime minister.

He finally left frontline politics, apparently for good, when Labour lost the 2010 general election.

Despite his complete lack of diplomatic experience, Mandelson was appointed the UK’s ambassador to Washington a year ago.

He quickly established a rapport with President Donald Trump and was a key figure in negotiations on a UK/US trade deal and technology partnership.

Mandelson also helped to smooth over American concerns around the UK government’s decision to hand sovereignty over the strategically-important Chagos Islands to Mauritius.

His return to the heart of British politics was seen as a reward for his years of behind-the-scenes work with Morgan McSweeney – now Starmer’s chief of staff – to help return Labour to government.

McSweeney is known to have pushed the PM to give Mandelson the ambassador’s role, a judgement call which has intensified calls from Labour MPs for him to be sacked.

The nature of their friendship has come out in drips and drabs over the years. Here’s a breakdown of what is currently public knowledge – and when it was first revealed.

A Financial Times report from June 2023 unveiled how an internal JP Morgan report, dating back to 2019, noted Epstein’s “particularly close relationship with Prince Andrew the Duke of York and Lord Peter Mandelson, a senior member of the British government”.

The report was commissioned to shed light on JPMorgan’s 15-year relationship with Epstein and refers to a range of meetings between the disgraced financier and Mandelson.

The dossier also found Mandelson had stayed at Epstein’s lavish townhouse in Manhatten when he was the UK’s business secretary while the convicted criminal was in prison for soliciting underage sex from a minor.

Mandelson was appointed as US ambassador in February last year, after going through routine due diligence and security vetting.

When asked about his Epstein connection by the Financial Times’ George Parker during an extensive interview, the former Labour cabinet minister said: “I regret ever meeting him or being introduced to him by his partner Ghislaine Maxwell.”

Maxwell is currently in prison for recruiting and trafficking underaged girls for the financier.

Mandelson added: “I regret even more the hurt he caused to many young women.”

However, according to the FT report, “an icy chill” then descended during their conversation on the train, and Mandelson added: “I’m not going to go into this. It’s an FT obsession and frankly you can all fuck off. OK?”

When later asked about Mandelson’s language, the prime minister’s spokesperson told reporters: “The prime minister has made clear the expertise and the experience Lord Mandelson has in relation to becoming ambassador to the US.”

The seeds of Mandelson’s political demise were sown last autumn, when US lawmakers released a tranche of documemts relating to Epstein.

They included a “birthday book” which contained a message from Mandelson in which he described Epstein as his “best pal”.

But it was a further revelation, that Mandelson told Epstein in an email that “your friends stay with you and love you” even as he was facing child underage sex charges in 2008, that proved to be the final straw.

Despite telling MPs that he had “confidence” in his ambassador, Starmer eventually sacked Mandelson, just seven months after appointing him.

“The emails show that the depth and extent of Peter Mandelson’s relationship with Jeffrey Epstein is materially different from that known at the time of his appointment,” the Foreign Office said.

Despite being sacked in disgrace, Mandelson appeared poised to make another remarkable comeback thanks to a series of high-profile media appearances at the start of this year.

They included an interview on Sunday with Laura Kuenssberg, the BBC’s flagship political programme.

However, he caused outrage when he failed to apologise to Epstein’s victims, saying only that he was sorry “for a system” which did not listen to victims’ voices.

“That system gave him protection but not them,” he said. “If I had not known, or if I was in any way complicit or culpable, of course I would apologise for it.”

After an angry backlash, Mandelson rowed back the following day, saying: “I did not want to be held responsible for his [Epstein’s] crimes of which I was ignorant, not indifferent, because of the lies he told me and so many others.

“I was wrong to believe him following his conviction and to continue my association with him afterwards. I apologise unequivocally for doing so to the women and girls who suffered.”

A new tranche of documents from the US’s Department of Justice (DoJ) came out at the start of February and finally sealed Mandelson’s fate.

They appeared to show he had accepted $75,000 from the disgraced financier between 2003 and 2004, though Mandelson has said he has no recollection of receiving those payments and did not know if the documents were genuine.

But amid mounting public anger, he announced he was quitting the Labour Party to avoid “further embarrassment” last Sunday.

The scandal has only intensified since then, with Mandelson now facing a criminal investigation over allegations he passed market sensitive information to Epstein when he was business secretary and the government was dealing with the aftermath of the global financial crash.

Responding to the revelations, Starmer said Mandelson had “betrayed” Britain.

Other emails show Mandelson and Epstein sharing crude jokes when the latter was released from prison – an occasion described as “Liberation Day” by the peer.

Mandelson announced last Tuesday that he was quitting the House of Lords, although it will require a special law to be passed to formally remove his title.

In a self-pitying interview with The Times carried out before the latest revelations, he tried to portray himself as a victim over his sacking as US ambassador.

“It was like a 5.30am drive-by shooting,” he said. “I was at the edge of something. Suddenly, I was put at the centre of it — as a result of historical emails of which I have no memory and no record.”

Suggesting he still had a contribution to make to British politics, he said: “Hiding under a rock would be a disproportionate response to a handful of misguided historical emails, which I deeply regret sending.

“If it hadn’t been for the emails, I’d still be in Washington. Emails sent all those years ago didn’t change the relationship that I had with this monster.

“I feel the same about the recent download of Epstein files, none of which indicate wrongdoing or misdemeanour on my part.”

After a Labour rebellion, the government has agreed to publish all documents relating Mandelson’s appointment as ambassador.

It’s thought there could be close to 100,000 government files related to the former Labour peer.

The police inquiry into Mandelson is also likely to continue for months, if not years, drawing out the political pain for Starmer and his government.

Scotland Yard confirmed on Friday they are searching two properties in their investigation, but Mandelson has not been “arrested and enquiries are ongoing”.

Questions about Starmer’s judgment – which was already in doubt after a slew of government U-turns – have only intensified over the Mandelson scandal.

While the PM says he was lied to by Mandelson, his critics say the warning signs were already there long before the decision was taken to send him to Washington.

Harriet Harman, for the former Labour deputy leader and a party loyalist, told the Electoral Dysfunction podcast: “He’s got to stop blaming Mandelson and saying ‘he lied to me’ because actually he should never have been considering him in the first place.

“And to say ‘he lied to me’ makes it look weak and naive and gullible. So it’s just completely the wrong thing.”

She added: “If he doesn’t take the path which is necessary, yes, this will finish him off and that will be a tragedy for the government, a tragedy for the country and tragedy for Keir Starmer.”

Mutinous Labour MPs believe Morgan McSweeney’s sacking is a necessary first step in repairing the huge political damage caused by the Mandelson scandal.

However, questions about Starmer’s own future continue to swirl, and are only likely to intensify in the days ahead.

One MP told HuffPost UK: “Taking refuge in constituency stuff this weekend seems appealing.

“But trying to pretend it’s all a bad dream for a few days won’t work, as constituents will be taking the chance to make very clear how they feel about Starmer and Mandelson and that’ll end up feeding into things back in parliament next week.”

While his rivals sharpen their knives, Starmer tried to win back public favour by issuing a frank apology on Thursday, telling Epstein’s victims he’s “sorry” for ever believing Mandelson.

Will it be enough to save him, or is this scandal going to bring him down?

A growing list of Labour backbenchers are speaking out against Keir Starmer over the Peter Mandelson scandal – while some are turning on each other.

The prime minister apologised for believing the ex-Labour peer’s “lies” over his relationship with dead paedophile Jeffrey Epstein on Thursday in an attempt to win back public favour.

But scrutiny over his decision to appoint Mandelson as the UK’s ambassador to Washington continues to grow, especially as their friendship was public knowledge even before Starmer gave him the plum job.

Labour MPs began the week by privately slamming the prime minister but now – after Starmer still insisted he had no reason to believe Mandelson had misled him over his Epstein ties until US lawmakers released new files on the convicted sex offender – a growing number of those on the left of the party are going on the record with their criticisms.

Paula Barker told the BBC she was “deeply ashamed” of the government’s initial attempts to block the release of documents surrounding Mandelson’s appointment.

However, she said “there’s nobody who I would be prepared to back at this stage” to replace him.

Simon Opher also told the New Statesman that Starmer’s chief of staff Morgan McSweeney – a close ally to Mandelson – “needs to go”, blaming the “poor decision-making of those around the prime minister” for the current crisis.

Bell Ribeiro-Addy told ITV News that appointing Mandelson was an “unforgivable betrayed of our stance on violence against women and girls”.

Others, like Neil Duncan-Jordan, went further, calling for the “Number 10 operation in its entirety” to change.

Similarly, Kim Johnson said: “If this is their idea of leadership, No.10 needs gutting from top to bottom.”

Jo White, leader of Labour’s Red Wall group, said on X: “The only way through this is an ethical reset at the heart of government. ”

And former Labour shadow chancellor John McDonnell warned: “This could bring this government down.

“It could certainly bring Keir Starmer down and this whole team around him, that’s the seriousness of it.”

Rachael Maskell, a known Labour rebel, said on Thursday: “We need to now move forward as a party to ensure that we can gain that support back.

“I don’t believe we can with the PM in place – it is inevitable that the PM is going to have to step down.”

But Loyalist MP Luke Akehurst played down the impact of these statements, saying: “I’m not sure Morgan McSweeney should lose much sleep over this small collection of my PLP colleagues, all policy rebels on various issues, calling for his departure.

“The same names repeatedly take the opportunity to share their hot takes with the media.”

This sparked further disquiet within the party as fellow MP and government critic Karl Turner hit back.

Replying on X, he said: “I don’t think McSweeney will give a monkeys, Luke. But our PM should. And so should you. We aren’t some sort of fast food franchise. We are the Labour Party.

“Getting clever like this about those of us that have got the bottle to speak says more about you than it does about me.”

Meanwhile, a Labour source was exasperated to see the chaos erupting within the party, telling HuffPost UK: “Why are they publicly fighting? What’s wrong with them all?”

Taylor Swift’s has unveiled the music video for her song Opalite, and you just might recognise some of the famous faces making surprise appearances.

On Friday, the Grammy-winning star shared her new video on both Apple Music and Spotify (ahead of its wider release on YouTube later this week), with cameos from everyone to Cillian Murphy to Graham Norton.

However, it turns out there’s more to the seemingly random selection of stars than it might appear.

Back in October, the Anti-Hero singer appeared on The Graham Norton Show to promote her latest album The Life Of A Showgirl, where she was joined on the couch by Greta Lee, Jodie Turner-Smith, Domhnall Gleeson, Lewis Capaldi and the Oscar-winning Oppenheimer actor.

And what do you know – that group of celebs also happens to be the cast of the Opalite music video.

Following Opalite’s release, Taylor told her social media followers that the idea for the video was sparked by a joke from the About Time actor.

“Domhnall made a light hearted joke about wanting to be in one of my music videos,” she recalled. “He’s Irish! He was joking! Except that in that moment during the interview, I was instantly struck with an idea.”

Indeed, Domhnall’s joke turned into him receiving a fully-fledged video treatment from Taylor a week later, with him in the starring role as her lover in the 90s-themed video that revolves around “Opalite”, a mysterious product plugged by Cillian’s character.

She shared: “I had this thought that it would be wild if all of our fellow guests on the Graham Norton show that night, including Graham himself, could be a part of it too.

“Like a school group project but for adults and it isn’t mandatory. To my delight, everyone from the show made the effort to time travel back to the 90s with us and help with this video.

“I had more fun than I ever imagined – made new friends, metaphors and fashion choices. It was an absolute thrill to create this story and these characters.”

Taylor is well-known to recruit her celebrity friends to star in her music videos.

Her Bad Blood release back in 2015 famously featured a female line-up that included Selena Gomez, Jessica Alba, Gigi Hadid and Zendaya, while years later, she recruited the likes of Katy Perry, RuPaul, Ellen Degeneres and Ciara to appear alongside her in her You Need To Calm Down video.

The Opalite video is currently available to watch on Spotify and Apple Music.
