Kemi Badenoch has urged Labour MPs to prioritise the national interest over party loyalty and back a parliamentary investigation into whether Prime Minister Keir Starmer misled the House of Commons over his appointment of Peter Mandelson as US ambassador. The vote, scheduled for Tuesday evening, could trigger a political crisis if the government suffers defeat, potentially threatening Sir Keir's leadership.
Downing Street launched an intense lobbying effort on Monday night, warning Labour MPs they would face a three-line whip to ensure compliance. However, writing in the Daily Mail, Mrs Badenoch argued that MPs of all parties have a duty to hold the Prime Minister accountable for treating Parliament with 'contempt'. She told Labour backbenchers they are 'not in the Commons simply to protect the PM from embarrassment'.
'Labour MPs now face a test of their own,' the Conservative leader said. 'They can circle the wagons, obey the Whips and tell themselves this is just politics. Or they can remember they are MPs before they are members of the Labour Party.'
Mandelson Scandal Deepens
Sir Keir faces intense scrutiny over his handling of the Mandelson affair. He is accused of misleading Parliament by repeatedly claiming that 'full due process' was followed, despite Mandelson being appointed before security vetting was completed. Mrs Badenoch also questioned the Prime Minister's assertion that 'no pressure whatsoever' was applied to officials to expedite the appointment.
Former Foreign Office chief Sir Philip Barton is expected to testify before MPs on Tuesday morning, corroborating claims that he warned against sending Mandelson to Washington. He is also likely to support his successor, Sir Olly Robbins, who stated that officials were 'under constant pressure' from Number 10 to approve the appointment. In a significant development, former Foreign Office security chief Ian Collard backed Sir Olly's account of pressure from Downing Street to fast-track Mandelson's vetting.
Commons Debate and Political Fallout
Opposition MPs are seeking an investigation by the Commons Privileges Committee into whether Sir Keir misled Parliament. Speaker Sir Lindsay Hoyle granted an emergency debate, a rare move, citing support from 'numerous MPs from across the House'. This process mirrors the one used by Sir Keir to force Boris Johnson out of Parliament over Partygate, though the Prime Minister insists his case is 'completely different'.
Sir Keir described the vote as a 'political stunt' and urged Labour MPs to stand together. 'Tomorrow is pure politics and we need to stand together against it,' he told the Parliamentary Labour Party. 'It's important to see the bigger picture here. They want to stop this Labour Government. When we stick together and fight together we are so much stronger.'
The Prime Minister has struggled to contain the backlash, having pressed ahead with Mandelson's appointment despite written warnings about his 'particularly close' relationship with convicted paedophile Jeffrey Epstein and questionable business ties in Russia and China. Sir Keir attempted to deflect blame by sacking Sir Olly Robbins, but has failed to convince MPs or even Cabinet members of his version of events.
Deputy Prime Minister David Lammy confirmed he warned against the appointment, stating there were 'worries at the time' and 'a discussion within government'. Liberal Democrat MP Lisa Smart urged Labour MPs to 'put principle before party and vote to refer Keir Starmer to the Privileges Committee'.
Conservative MP Sir Desmond Swayne described the potential use of a three-line whip as 'an abomination', arguing that MPs should have a free vote on matters of parliamentary truth. Despite this, Labour Whips are expected to warn MPs that failure to back Sir Keir could result in suspension from the party.
Number 10 released a letter from former permanent secretary Sir Chris Wormald, stating that 'appropriate processes were followed' in Mandelson's appointment. However, Mrs Badenoch dismissed this as 'irrelevant', noting that Sir Chris's predecessor, Simon Case, had advised the PM not to announce the appointment until security vetting was completed—advice that was ignored. MPs were informed that tens of thousands of files relating to Mandelson, which Parliament requested in February, will not be released until after the local elections.
