Sir Keir Starmer's leadership is under increasing threat as the fallout from the Peter Mandelson scandal compounds dismal opinion poll ratings, leaving Labour MPs fearing for their seats. The Prime Minister survived Wednesday's Commons statement on the vetting saga, but his authority has been severely damaged after being forced to cede control of documents to the Intelligence and Security Committee.
Labour's poll ratings have plummeted, with the rise of Reform UK on the right and the Greens on the left eroding support. Policy missteps on winter fuel payments, welfare reforms, and digital ID, along with ongoing issues over Channel migrant crossings and sluggish economic growth, have strained relations between No 10 and MPs. The Mandelson affair, involving his appointment as US ambassador and links to Jeffrey Epstein, has added to the gloom.
A by-election in the previously safe Labour seat of Gorton and Denton on February 26 could see the Greens or Reform claim victory. May's elections threaten Labour's control in Wales and difficult contests in England, while in Scotland, Anas Sarwar struggles against the UK-wide slump. A poor showing could trigger a move against Starmer.
To oust Starmer, a challenger would need the support of 80 MPs (20% of the parliamentary party) to trigger a contest. Allies insist he would fight any challenge, but a more likely exit route might be resignation if enough senior figures withdraw support. Potential successors include former deputy leader Angela Rayner, Health Secretary Wes Streeting, Home Secretary Shabana Mahmood, former leader Ed Miliband, or Greater Manchester mayor Andy Burnham, though Burnham's path back to Parliament is blocked.
