Finally breaking his silence since sacking the US ambassador last week, the premier struggled to address questions about what he knew and when.

Sir Keir finally broke cover in an interview in which he insisted he would never have appointed the controversial peer as US ambassador if he had known the full truth about his friendship with Epstein.

“Had I known then what I know now, I’d have never appointed him,” the UK Prime Minister said.

Lord Mandelson's friendship with Jeffrey Epstein led to the ambassador's downfall, and now the prime minister's judgment is being questioned.

U.K. prime minister says former ambassador’s responses to questions from his officials were not “at all satisfying” before sacking last week.
