Overview
- On Monday, June 22, Keir Starmer announced he would step down as Labour leader and prime minister, told King Charles III, will stay in office as interim and asked the party’s National Executive Committee to open nominations on 9 July.
- Starmer said he had lost the support of his parliamentary party after months of weak growth, rising living costs, pressure on public services and controversies including the appointment of Peter Mandelson; several cabinet ministers had urged a timetable for change.
- Andy Burnham, who won the Makerfield by‑election to return to the Commons, has declared his candidacy and is widely reported to have backing well above the 81 MPs needed to qualify for the ballot.
- Labour expects to complete the succession before Parliament reconvenes in September so the new leader would become prime minister without an immediate general election while the party retains its Commons majority.
- The leadership change creates short‑term political uncertainty, raises the prospect of policy shifts to counter gains by Reform UK, and will be watched closely by voters, unions and investors for signals on the economy and public services.
