Former British Ambassador to the US Lord Peter Mandelson, who was fired over his ties to Jeffrey Epstein, has been arrested on suspicion of misconduct in public office, police in London said Monday. The ex-diplomat, 72, was seen being led out of his London home by cops Monday afternoon after he was accused of leaking sensitive British government intelligence to the pedophile financier. Mandelson, who infamously appeared in the Epstein files in just his underwear and a T-shirt, looked stony-faced as he was put in the back of an unmarked car.
