Peter Mandelson, Britain’s former ambassador to the U.S., resigned from the U.K.’s ruling Labour Party to avoid causing it “further embarrassment” after the latest revelations about his links to the disgraced financier Jeffrey Epstein.

Mandelson is facing questions about payments totaling ?75,000 ($103,000) made to him and his partner by Epstein in 2003 and attempts to stop the U.K. from introducing a tax on bankers’ bonuses in 2009 after a request from Epstein.

The disclosures, which include more compromising pictures of Mandelson, came in the latest release of the Epstein files by the U.S. Department of Justice last week.
