PM won't face inquiry over claims he misled MPs on Mandelson vetting
The House of Commons rejected a Conservative motion to trigger a Privileges Committee inquiry into claims that Prime Minister Keir Starmer misled MPs about the vetting of Lord Mandelson for the US ambassadorial post. The vote followed a Commons debate in which Labour MPs were divided and the government campaigned to secure support. The discussion arrived after a Foreign Affairs Committee hearing into the vetting process, where officials acknowledged the decision process and past advisers admitted mistakes.
Why It Matters
The result determines whether the PM could face parliamentary consequences over alleged misleading statements and highlights ongoing scrutiny of Mandelson’s appointment and its vetting process.

Parliamentary vote on motion to trigger inquiry
April 28, 2026
The Commons voted 335 to 223 against a Conservative-led motion seeking to trigger a parliamentary inquiry into whether Prime Minister Keir Starmer misled MPs about the vetting process for Lord Mandelson’s US ambassadorship. The debate began with Kemi Badenoch arguing the PM had not followed full due process and that the Ministerial Code requires correction if the record is not accurate. Labour MPs largely opposed the motion, with 14 rebels in support and one MP voting both aye and no (an apparent abstention). The Lib Dems, SNP, Greens, DUP, Plaid Cymru, Reform and nine independents also voted with the Tories. About 53 Labour MPs had no recorded vote. Emma Lewell criticized the government's stance and called for the PM to refer himself to the Privileges Committee to clear his name. Labour MPs campaigning in Scotland were recalled to Westminster to participate.
Foreign Affairs Committee hearing on Mandelson vetting
April 2026
The Foreign Affairs Committee heard further evidence about the vetting process for the US ambassador role. Senior civil servant Sir Philip Barton said he was not consulted by Downing Street before the decision and noted the appointment could be a difficult issue due to Mandelson's links to Epstein. Morgan McSweeney, the PM's former chief of staff, told MPs he had made a serious mistake in recommending the appointment and said No 10 wanted Mandelson in post quickly but officials were not asked to skip steps.
