Prime Minister Keir Starmer faces intensifying pressure to resign amid historically low approval ratings—net -48% in March 2026 polls—and internal Labour Party dissent, fueled by the mid-March release of files showing he overruled reputational risk warnings on a controversial Peter Mandelson appointment. Speculation of a leadership challenge has grown, with MPs like Clive Lewis warning that not removing him could prove disastrous, though cabinet allies such as Wes Streeting urge unity. Traders focus on the May 7 local, Scottish, and Welsh elections, where projected heavy Labour losses could trigger a no-confidence vote, party revolt, or snap leadership contest, against a backdrop of immigration policy backlash and economic woes. Starmer has vowed to "never walk away," but his mandate remains vulnerable to further scandals or electoral setbacks.
