MPs to Vote on Potential Investigation of UK Prime Minister Starmer Over Mandelson Appointment

The House of Commons is set to vote on a motion to refer Prime Minister Keir Starmer to the privileges committee for an investigation into whether he misled MPs about the appointment of Peter Mandelson as UK ambassador to the US. Speaker Sir Lindsay Hoyle announced on Monday that he would allow the vote, stating, "I have taken advice and I will let the House decide."

Peter Mandelson was appointed in September 2025 but was later removed from the role due to concerns over his past links to Jeffrey Epstein, who was convicted of child sex offenses in 2008. Starmer told the Commons on three occasions that due process was followed in Mandelson's hiring, including statements on October 15, 2025, November 12, 2025, and December 3, 2025, according to parliamentary records.

" The Foreign Affairs Committee is conducting an inquiry into the appointment process. Morgan McSweeney, Starmer's former chief of staff who resigned amid the controversy, is scheduled to testify before the committee on Tuesday.

Philip Barton, former permanent secretary at the Foreign, Commonwealth and Development Office (FCDO), is also set to appear before the committee on Tuesday. Olly Robbins, a senior FCDO official, was dismissed by Starmer last week after it emerged that the vetting agency had recommended against granting Mandelson security clearance, and Robbins did not inform the prime minister.

Ian Collard, the FCDO's director of security who briefed Robbins, submitted written evidence to the committee on Monday. " Collard will provide evidence in writing only and not appear in person, as confirmed by the committee.

" Local and devolved elections are scheduled for May 7, 2026.

Starmer urged Labour MPs to "stick together and fight together" ahead of the vote. Labour whips have instructed MPs to vote against the Conservative motion, according to party sources.

The privileges committee has not commented on the motion as of April 27, 2026. No publicly released evidence from the vetting agency has detailed the specific reasons for the recommendation against Mandelson's clearance beyond the Epstein links.
