Labour MPs are examining the procedures for mounting a potential leadership challenge against Sir Keir Starmer, according to reports from Westminster sources. The discussions come as the party faces pressure over its handling of economic policy and leadership direction.

Chancellor Rachel Reeves has reportedly warned Labour MPs that any leadership instability could damage the UK economy, which she says has shown resilience despite ongoing Middle East tensions. Reeves expressed concerns that political uncertainty within the party could undermine economic confidence at a critical time.

Several potential candidates are being mentioned in Westminster circles as possible challengers. Health Secretary Wes Streeting is reported to believe he has sufficient support among MPs to mount a credible campaign, while Deputy Prime Minister Angela Rayner has addressed questions about her tax affairs that could have complicated any leadership bid.

Under Labour Party rules, a leadership contest can be triggered if a sufficient number of MPs submit a motion of no confidence in the current leader. The exact threshold and procedures would depend on the party's constitutional arrangements at the time any challenge is mounted.

The speculation reflects broader tensions within the Labour Party over strategy and direction, though no formal challenge has been announced. Party sources suggest the discussions remain at an early stage, with no immediate timeline for any potential contest.
