Conservative leader Kemi Badenoch has called on Labour MPs to support an investigation into whether Prime Minister Keir Starmer misled Parliament concerning the appointment of Peter Mandelson as US ambassador. The vote, scheduled for Tuesday evening, could have significant consequences for Starmer’s leadership.

Pressure Mounts on Starmer

Badenoch argues that Labour MPs should prioritize national interests over party loyalty and hold Starmer accountable for alleged contempt of Parliament. She urged Labour backbenchers in a Daily Mail article to represent their constituents and transcend partisan politics.

Allegations of Misleading Parliament

The proposed inquiry will examine whether Starmer knowingly provided false information when he stated that Mandelson underwent proper vetting before his appointment. Critics claim Starmer misled MPs by asserting ‘full due process’ was followed, despite evidence suggesting Mandelson was appointed before security checks were completed.

Evidence and Testimony

Badenoch also questioned Starmer’s claim that no pressure was applied to officials to expedite Mandelson’s vetting. Former Foreign Office chief Sir Philip Barton is expected to testify that he advised against the appointment.

Corroborating Accounts

This testimony would corroborate claims from his successor, Sir Olly Robbins, that officials faced pressure from No. 10 to approve Mandelson. Former security chief Ian Collard has also alleged that Downing Street pressured officials to fast-track the vetting process.

Key Witnesses and Political Reactions

Starmer’s former chief of staff, Morgan McSweeney, is also set to provide evidence. Opposition MPs are seeking a Privileges Committee investigation, which Starmer dismisses as a political tactic. Commons Speaker Sir Lindsay Hoyle granted an emergency debate due to cross-party support.

Concerns Over Mandelson's Background

Starmer has defended his government’s transparency but faces criticism regarding Mandelson’s ties to Jeffrey Epstein and business dealings in Russia and China. Despite attempts to blame officials, including the dismissal of Sir Olly, Starmer has struggled to convince MPs and his Cabinet of his innocence.

Potential Outcomes

Deputy Prime Minister David Lammy admitted to voicing concerns about Mandelson’s appointment, further weakening Starmer’s position. Liberal Democrat MP Lisa Smart urged Labour MPs to prioritize integrity, while allies of Angela Rayner hinted at a potential abstention. The outcome of the vote could significantly reshape the political landscape.
