When the US Justice Department dropped three million pages of Epstein-related documents on January 29, nobody expected the fallout to spread quite this far, quite this fast. But here we are, watching a full-blown political crisis unfold across Europe, complete with arrests, resignations, and bond market chaos that's making investors increasingly nervous about UK government debt.

The latest bombshell: Andrew Mountbatten-Windsor, brother of King Charles, has been arrested on suspicion of misconduct in public office. Bloomberg reported the arrest today, noting that Thames Valley Police have not yet filed charges. His arrest follows fresh details about his relationship with convicted sex offender Jeffrey Epstein that emerged from the document dump.

This comes just weeks after Lord Peter Mandelson, a prominent British political insider, quit the Labour Party on February 2 and resigned from the House of Lords the next day. The reason? The Epstein files revealed he had leaked confidential government information to Epstein and received $75,000 in payments. What makes this particularly awkward for Prime Minister Keir Starmer is that he appointed Mandelson as US ambassador in September 2025 despite knowing about his ties to a convicted sex offender.

The scandal isn't confined to Britain. Norwegian authorities charged former Prime Minister Thorbjørn Jagland on February 13 with "gross corruption" related to his Epstein connections. In France, Jack Lang, a former culture minister, resigned from the Arab World Institute as investigations into his relationship with Epstein intensified.

The timing couldn't be worse. Europe's economy is already struggling, with the Eurozone posting just 1.3% year-on-year growth in the fourth quarter and industrial production dropping 1.4% month-on-month in December. Combined with mounting public frustration over mass immigration, the weak economic backdrop creates fertile ground for right-leaning political parties to gain support.

Former White House lawyer Richard Painter captured the mood when he told NPR that the European elite's connections to Epstein are "very humiliating." That humiliation quickly translated into market anxiety.

Bond Traders Lose Confidence in UK Debt

When political stability gets shaky, bond markets tend to notice. And they definitely noticed this time. Traders turned cautious on UK government debt as the Epstein scandal escalated. The spread between two-year and 10-year gilt yields widened to 86 basis points on February 6, the largest gap since 2018.

Three days later, the 10-year gilt yield climbed to 4.569%, up 5 basis points on the day. That might not sound dramatic, but rising long-term yields mean the UK government will pay more to borrow money going forward as investors demand a higher premium for the added risk.

Jordan Rochester, Head of Fixed Income, Currencies & Commodities Strategy at Mizuho EMEA, warned in a February 9 interview that gilts could become "subject to the whims of random political headlines." That's not the kind of thing you want to hear about your country's sovereign debt.

The FTSE 100 dipped into the red intraday on February 8 before rebounding 0.2% to close at 10,386.23, near a record high and up 4.4% year-to-date. By Monday, ten-year gilts had fallen below 4.5% as Starmer secured cabinet support and political risks appeared to ease somewhat.

Senior Advisers Exit as Crisis Deepens

The documents released on January 29 showed that Mandelson had forwarded confidential 2009-2010 memos to Epstein about €500 billion in European Union bailouts, asset sales, and tax changes. In March 2010, he shared details of meetings between former UK Chancellor Alistair Darling and Larry Summers, who was President Barack Obama's Director of the National Economic Council at the time.

Metropolitan Police launched a criminal investigation into Mandelson on February 3 and searched two London properties connected to him as part of the probe.

The political damage to Starmer has been severe. Within 72 hours earlier this month, his Chief of Staff, Morgan McSweeney, resigned. A day later, his Communications Director, Tim Allan, stepped down. Both became casualties of the Epstein fallout.

Starmer told Parliament that Mandelson "lied repeatedly" about his Epstein ties. "I've agreed with His Majesty the King that Mandelson should be removed from the list of privy counselors on the grounds that he's brought [disgrace]."

Weak Economy Amplifies Political Pain

Political crises hurt more when the economy is already limping along. The British economy expanded just 0.1% in the fourth quarter, according to February 12 data from the Office for National Statistics. That missed the 0.2% consensus forecast.

The EY ITEM Club expects UK GDP to grow by 0.9% in 2026, a marginal upgrade from the 0.8% predicted in November's Autumn Forecast, before accelerating to 1.3% in 2027 and settling at 1.4% from 2028 onwards. Those aren't exactly inspiring numbers.

Meanwhile, the country's unemployment rate rose to 5.2% in the three months ending December 2025, slightly above market expectations. That's the highest level since the three months ending February 2021.

Betting Markets Give Starmer Rough Odds

The scandal is piling onto already dismal approval ratings for Starmer. He has recorded the lowest likeability rating among UK politicians, with over 70% of people saying they dislike the Prime Minister, according to Ipsos data released on February 6.

Reform UK leader Nigel Farage took aim at Starmer during a Birmingham event on February 9, declaring that the "political life of the most unpopular and most useless prime minister in living memory is drawing to a close."

Nigel Green, CEO of London-based deVere Group, warned that if "the Mandelson affair brings down Starmer, the consequences would not stop at Downing Street. Markets would immediately focus on the UK bond – or gilt – market."

Polymarket, a crypto-powered betting platform focused on political and cultural events, is pricing in a 68% probability of Starmer leaving office by June. That's a remarkable number for a sitting prime minister.

Corporate World Cuts Ties Quickly

The UK's Financial Conduct Authority hasn't yet commented on whether it will investigate Mandelson, but corporate clients aren't waiting around to find out. They're cutting ties preemptively.

Former Prime Minister Gordon Brown said on February 8 that Mandelson's Epstein connections constituted a "financial crime." The Liberal Democrats urged the FCA to launch insider-trading investigations.

Barclays PLC (BCS) dropped Mandelson's Global Counsel firm in response to the Epstein revelations. Mandelson co-founded Global Counsel with Benjamin Wegg-Prosser in 2010.

The firm's client list has included some serious names: JPMorgan Chase & Co (JPM), Barclays, Shell plc (SHEL), GlaxoSmithKline plc (GSK), and OpenAI.

Wegg-Prosser resigned as CEO of Global Counsel on February 6. Rebecca Park bought out Mandelson's 21% stake for an undisclosed sum.

Scandal Reaches Beyond Britain

French prosecutors have opened investigations into Lang and his daughter Caroline for "aggravated tax fraud and laundering." Lang has denied all allegations through his lawyer, Laurent Merlet, calling them "inaccurate" and "unfounded conflations."

In Norway, authorities charged Jagland after the Council of Europe lifted the diplomatic immunity he enjoyed from his past role. His lawyer says he has denied criminal liability and is willing to cooperate with investigators.

Emails released by the US government suggest Jagland planned solo and family visits to Epstein's homes in Paris, New York, and Palm Beach after the billionaire was convicted of a child sex offence.

Norwegian Ambassador Mona Juul resigned following revelations that Epstein left her children $10 million in his will. Juul acknowledged in a statement to Norwegian news agency NTB that it had been "imprecise" to describe her contact with Epstein as minimal.

Norwegian Royal Family Drawn In

Norway's Crown Princess Mette-Marit appeared over 1,000 times in the Epstein files. She stayed in touch with him through 2014 despite knowing his past "didn't look good," according to the documents.

She visited his mansion, called him "sweetheart," and exchanged pictures of naked women, according to the US documents.

Tove Taalesen, royal correspondent for Oslo-based Norwegian newspaper Nettavisen, said that "confidence in the Crown Princess has fallen sharply. A majority still backs the institution, but that support is weaker, and uncertainty is growing."

With investigations widening across multiple countries and political pressure mounting, Europe's leaders are dealing with a scandal whose full impact remains unclear. What is clear: financial markets don't like uncertainty, voters don't like feeling deceived, and both are watching closely to see who falls next.
