British lawmakers voted on Tuesday against launching an inquiry into whether Prime Minister Keir Starmer misled parliament in statements about his decision to appoint Peter Mandelson as ambassador to the United States.

Starmer picked Labour veteran Mandelson for the top diplomatic posting in December 2024 and then sacked him last September when his ties to the late U.S. sex offender Jeffrey Epstein were found to have been deeper than previously known.

The prime minister has resisted pressure to quit over the matter, saying Mandelson lied about his relationship with Epstein. Starmer also said officials had kept information from him about the vetting process that would have stopped him making the appointment.

On Tuesday, lawmakers voted 335 to 223 against asking the Committee of Privileges to investigate whether Starmer had misled the House of Commons on several matters, including by saying “full due process” had been followed around the appointment.
