Epstein died by suicide in a jail cell in 2019, while awaiting trial on US federal charges accusing him of sexually abusing dozens of girls.

Starmer never met Epstein and is not accused of any wrongdoing. But the prime minister is under intense pressure over the appointment after newly released documents revealed fresh details of Mandelson’s close relationship with Epstein.

“I was lied to,” Starmer said. “It had been publicly known for some time that Mandelson knew Epstein, but none of us knew the depth and the darkness of that relationship.” British police are investigating Mandelson over potential misconduct in public office. He is not accused of any sexual offences.

Documents published last week by the US Department of Justice contain new revelations, including papers suggesting Mandelson shared sensitive government information with Epstein after the 2008 global financial crisis. There are also scores of chatty, jokey messages pointing to a much closer relationship than Mandelson had previously disclosed.

The newly released files also suggest that in 2003 to 2004, Epstein sent three payments totalling USD 75,000 to accounts linked to Mandelson or his partner Reinaldo Avila da Silva, now his husband.

Mandelson, 72, has been a major, and contentious, figure in the Labour Party since the 1990s. He twice had to resign from senior posts in previous administrations because of scandals over money or ethics.

He was chosen as ambassador because his trade expertise, network of contents and mastery of the political “dark arts” were considered assets in dealing with President Donald Trump’s administration.

Critics say Mandelson’s ties with Epstein made his appointment too risky and Starmer was, at best, naive.
“I think the prime minister has shown that his judgment is questionable,” Labour lawmaker Paula Barker said. “I think he has questions to answer. I think he has a very long way to go to rebuild trust and confidence with the public, and trust and confidence within our party.”
