Kemi Badenoch has written to Prime Minister Keir Starmer demanding “complete and truthful” answers over the controversy surrounding the appointment of Peter Mandelson as UK ambassador to the United States.
In the letter, sent ahead of Starmer’s expected statement to the House of Commons, the Conservative leader said she welcomed his decision to address MPs but raised concerns about what she described as earlier inaccuracies in his statements to Parliament.
Badenoch wrote that the Prime Minister had “not given accurate information to Parliament previously” and had failed to correct the record at the “earliest opportunity”. She argued that MPs should have been informed sooner about issues linked to Mandelson’s appointment.
The letter centres on the ministerial code, which requires ministers to provide “accurate and truthful information” to Parliament. Badenoch said the code also emphasises “candour and openness” and expects ministers to be as transparent as possible with both MPs and the public.
She accused Starmer of failing to answer “very simple questions” about what he knew and when, adding that such conduct was “contemptuous of Parliament” and fell short of the standards set out in his own code.
The Conservative leader also said there was a perception that the Prime Minister had been “at best recklessly negligent and at worst dishonest” in his handling of the issue, though she stopped short of making a formal allegation of deliberate misconduct.
Call for fuller disclosure
Badenoch said she would use Monday’s Commons session to press for clearer answers, stating that both Parliament and the public were entitled to “the truth, the whole truth and nothing but the truth”.
She urged the Prime Minister to avoid “evasion” and “digressions” in his statement, and instead provide a full account of the decisions surrounding Mandelson’s appointment.
The letter also criticised the broader handling of the affair, describing it as “tawdry and shaming” and arguing it had damaged the UK’s relationship with the United States.
National security concerns raised
Badenoch further claimed that appointing Mandelson despite reported security concerns had implications for national security. She said the role of ambassador to Washington was among the most sensitive diplomatic positions and required the highest level of scrutiny.
She also referenced Mandelson’s past links to convicted sex offender Jeffrey Epstein, arguing that the situation had caused offence and raised further questions about judgement.
Wider political implications
In her letter, Badenoch suggested the controversy reflected broader issues in how the government operates, arguing that it risked distracting ministers from key challenges, including the cost of living and national security.
She confirmed the letter had been copied to other party leaders in the Commons, noting previous concerns about the Prime Minister’s willingness to engage with parliamentary scrutiny.
The intervention comes as Starmer prepares to face MPs amid mounting political pressure over the Mandelson affair. His statement, along with upcoming committee evidence from former senior civil servant Olly Robbins, is expected to be a critical moment in determining how the controversy develops.
Keir Starmer is expected to speak at approximately 3pm – 3.30pm on Monday afternoon (although the exact time depends on parliamentary business). You can watch along online at Parliamentlive.tv or on regular TV channels.
