PM Not Subject to Parliamentary Inquiry on Mandelson Appointment Claims
Sir Keir Starmer will not undergo a parliamentary investigation regarding allegations that he misled MPs about the vetting process for Lord Mandelson's appointment as US ambassador.
The House of Commons voted 335 to 223 against a Conservative-led motion that sought to initiate the inquiry.
Some Labour MPs from the party's left wing argued that the Prime Minister should have referred himself to the Privileges Committee, but the majority opposed the motion following a coordinated effort by No 10 to secure their support.
Sir Keir has denied accusations that he misled MPs concerning whether the vetting for the US ambassador role followed "full due process" and his statement that "no pressure whatsoever" was exerted on Foreign Office officials.
Conservative Motion and Ministerial Code Context
Conservative Party leader Kemi Badenoch submitted a motion requesting that the Prime Minister's comments be reviewed by the cross-party committee responsible for investigating breaches of parliamentary rules by MPs.
The Ministerial Code mandates that ministers who knowingly mislead Parliament are expected to resign, while any inadvertent errors should be corrected "at the earliest opportunity." The Privileges Committee ruled in 2023 that former Prime Minister Boris Johnson had misled MPs about parties held in Downing Street during the Covid pandemic.
Badenoch criticized Labour MPs for dismissing the motion as a "stunt," suggesting they were "acting like sheep." However, some Labour MPs questioned the directive to oppose the motion, warning it risked appearing as a "cover-up." The division list revealed 14 Labour MPs rebelled to support the motion, with another MP voting both aye and no, typically considered a formal abstention.
It remains unclear what consequences, if any, those Labour MPs who defied No 10's instructions will face.
Labour MPs' Reactions and Internal Debate
South Shields MP Emma Lewell, one of the rebels, stated during the debate that the government's handling of the vote "smacks, once again, of being out of touch and disconnected from the public mood."
"It has played into the terrible narrative that there is something to hide and good, decent colleagues will be accused of being complicit in a cover-up."
Lewell added that Sir Keir should have referred himself to the committee "with a clear statement that he is doing so to clear his name."
Labour MP Rebecca Long-Bailey told BBC's Politics Live that a "moment of reckoning after the local elections" on 7 May could determine Sir Keir's future.
Conversely, several Labour MPs defended the government's stance during the debate. Gurinder Singh Josan described the call for a Privileges Committee referral as "premature," noting that the vetting process was under scrutiny elsewhere in Parliament. Cardiff West MP Alex Barros-Curtis said he did "not believe the case was made out" for the Conservative motion.
In an effort to ensure the motion's rejection, Labour MPs campaigning in Scotland ahead of upcoming elections were summoned back to Westminster.
Debate Highlights and Party Positions
Opening the debate, Badenoch scrutinized Sir Keir's defense of his remarks and emphasized the Ministerial Code's requirement for prompt correction of the record.
"It is very obvious that what the prime minister said at the despatch box was not correct. It's clear that full due process was not followed."
Senior cabinet minister Darren Jones accused Badenoch of "ranting incoherence" while defending Sir Keir's handling of the matter.
When pressed by Badenoch to reiterate the PM's claim that "no pressure existed whatsoever," Jones argued that Sir Keir's words should be understood "in the right context."
Jones was heckled by opposition MPs as he explained that Sir Keir was "specifically responding to the allegation that there was pressure that Peter Mandelson should not be vetted at all and that he should be sent to Washington regardless of the vetting outcome."
Liberal Democrat leader Sir Ed Davey stated the country requires a government focused on addressing cost-of-living issues, adding:
"Crucially it needs a government that it can trust."
SNP Westminster leader Stephen Flynn remarked that Labour MPs "cannot outrun Peter Mandelson, they cannot outrun their own prime minister and his record."
Reform UK deputy leader Richard Tice commented that Sir Keir "prides himself on process" but suggested an anecdotal culture contrary to that exists around and within him. Green MP Ellie Chowns asserted:
"It is clear that there is a case to answer here" for the Prime Minister.
Background on Mandelson Appointment and Vetting Process
Lord Mandelson began his role as Washington ambassador in February 2025 but was dismissed in September after Downing Street revealed new information regarding the extent of his relationship with the late sex offender Jeffrey Epstein.
Sir Keir has faced repeated inquiries about the appointment, including why the peer received security clearance from the Foreign Office despite vetting officials raising concerns.
The Commons debate followed further evidence presented to the Foreign Affairs Committee about the vetting process, including testimony from the senior civil servant at the Foreign Office at the time of the PM's decision to appoint Lord Mandelson.
Sir Philip Barton stated that no one in Downing Street consulted him before the decision and noted he considered the appointment a "potentially difficult issue" due to Mandelson's known links to Epstein.
"I was presented with a decision made by Sir Keir and told to get on with it."
Additionally, Morgan McSweeney, the PM's former chief of staff, admitted to MPs that he made "a serious mistake" in recommending Lord Mandelson's appointment.
McSweeney said No 10 wanted Mandelson in the post "quickly" but insisted officials were never asked to "skip steps."
