Members of the House of Commons will debate on Tuesday whether Keir Starmer should be investigated by the Committee of Privileges, the parliamentary privilege review committee, for misleading the House of Commons regarding the security clearance of Peter Mandelson.
Mandelson became US ambassador despite links to notorious sex offender Jeffrey Epstein.
Keir Starmer's Labour Party has a majority in the House of Commons, and, according to information provided to the BBC, its members have been urged to vote against an inquiry.
Conservative leader Kemi Badenoch has accused Starmer of misleading the House of Commons and called for Starmer's resignation.
A parliamentary inquiry was launched into Prime Minister Boris Johnson's actions during the Covid pandemic.
