Starmer Avoids Commons Probe Over Mandelson Vetting

The UK prime minister will not face a parliamentary investigation over accusations that he misled MPs about the vetting process used to appoint Peter Mandelson as ambassador to the United States.

The House of Commons voted by 335 to 223 against a motion brought by the Conservative Party seeking to refer the matter to the Privileges Committee, which examines potential breaches of parliamentary rules.

The vote followed a strong push by Downing Street to ensure Labour MPs opposed the proposal, although several members of the governing party broke ranks.

Commons vote and Labour divisions

Conservative leader Kemi Badenoch tabled the motion after questioning the prime minister’s statements to MPs about whether Mandelson’s appointment had gone through “full due process” and whether officials had faced any pressure during the vetting process.

Under the Ministerial Code, ministers who knowingly mislead Parliament are expected to resign, while inadvertent mistakes should be corrected as soon as possible.

Fourteen Labour MPs voted with the Conservatives in favour of the inquiry, while another cast votes on both sides, which is commonly treated as a formal abstention. The voting record also showed that 53 Labour MPs did not have a vote registered, which can occur when members are absent with permission or engaged in official duties.

Some Labour MPs expressed unease about opposing the motion. South Shields MP Emma Lewell, one of the rebels, told the debate the government’s handling of the issue risked appearing disconnected from public concerns.

She said the approach had fed perceptions that something was being concealed and argued the prime minister should have referred himself to the committee to clear his name.

Other Labour MPs defended the government. Cardiff West MP Alex Barros-Curtis said the Conservatives had failed to demonstrate sufficient grounds for launching an inquiry, while Gurinder Singh Josan described the move as premature because the appointment process was already being examined elsewhere in Parliament.

Opposition criticism

Opening the debate, Badenoch argued that the prime minister’s previous comments in the Commons were inaccurate and said the record should be corrected.

She said it was clear that the vetting process had not followed full procedure.

Senior cabinet minister Darren Jones rejected the accusation, saying the prime minister had been responding to claims that Mandelson had been sent to Washington without any vetting at all. Opposition MPs repeatedly interrupted Jones during his defence.

Opposition parties also used the debate to question the government’s credibility. Liberal Democrat leader Ed Davey said the country needed a government focused on addressing cost-of-living pressures and one the public could trust.

Scottish National Party Westminster leader Stephen Flynn said Labour MPs could not escape the controversy surrounding Mandelson’s appointment.

Scrutiny of Mandelson appointment

Mandelson took up the ambassadorial post in Washington in February 2025 but was dismissed in September after Downing Street said new information had emerged about the extent of his links with the late sex offender Jeffrey Epstein.

The prime minister has since faced repeated questions about the appointment, including why the Foreign Office granted Mandelson security clearance despite concerns raised by vetting officials.

During evidence to the Foreign Affairs Committee, senior civil servant Sir Philip Barton said Downing Street had not consulted him before the decision was made. He told MPs he had been presented with the choice and instructed to proceed with the appointment.

Morgan McSweeney, the prime minister’s former chief of staff, also told MPs he had made “a serious mistake” in recommending Mandelson for the role.

McSweeney said Number 10 had wanted the ambassador in place quickly but insisted that officials were never instructed to bypass the standard vetting steps.
