This afternoon, MPs will vote on whether Sir Keir Starmer should face a parliamentary investigation into the Mandelson vetting row.
Labour has a huge majority in Parliament, with 403 of the 650 seats, meaning a large number of MPs would need to turn on the prime minister for the vote to succeed.
But the BBC has been told that cabinet ministers have been ringing round Labour MPs to convince them to back the prime minister and vote against referring the matter to the Privileges Committee.
The BBC also understands that Labour MPs are likely to be whipped - i.e. told - to vote down the motion, rather than be given a free vote.
The prime minister has told the Commons that Lord Mandelson's vetting followed "due process"and that "no pressure whatsoever" was applied to officials at the Foreign Office. He has consistently denied accusations he misled MPs.
But Conservative leader Kemi Badenoch said Starmer had misled Parliament "multiple times" on the subject.
She urged Labour MPs to "look into their consciences" and back an inquiry by the Privileges Committee.
