The Daily Mail on Monday launched a reader poll asking whether Prime Minister Keir Starmer will remain in office beyond the general election scheduled for May 2026, as some Labour MPs openly warn the party leader could be vulnerable within months.
Starmer, who became the United Kingdom's first Labour prime minister since 2010 after taking office with a commanding Commons majority, faces renewed internal pressure after a turbulent year in which he pledged to build a "government of service." Questions among party figures have intensified this week amid controversy over the sacking of Lord Peter Mandelson as the United Kingdom's ambassador to the United States.
Labour MPs and party activists have identified next May's elections as a potential make-or-break moment for Starmer, with some warning that a strong performance by Nigel Farage's Reform UK could dent Labour's position further. The Daily Mail's poll invites readers to cast their vote on the question every day at 12 p.m., part of the title's regular "Poll of the Day" series.
Removing a sitting Labour leader requires a formal process within the party. At least 80 members of Parliament must nominate a potential replacement to trigger a card vote at the party's annual conference on whether to hold a full membership election for the leadership. Until such thresholds are met, Starmer remains firmly in place as prime minister.
The sacking of Lord Mandelson, a former cabinet minister and senior Labour figure, as ambassador to Washington has prompted scrutiny from inside and outside the party. Labour sources said the move has prompted questions among MPs about the judgment and direction of the government, though party officials have not publicly signalled any formal attempt to initiate a leadership contest.
Starmer's tenure to date has combined efforts to stabilise public services and present a distinct policy agenda after 15 years of Conservative government, but he has also contended with criticism over handling of individual appointments and political strategy. Opposition parties, including Reform and the Conservatives, have sharpened attacks on Labour's record ahead of next year's polls.
The Daily Mail published the poll on Sept. 15, 2025, offering readers a daily opportunity to register their view on whether Starmer will still be prime minister after the May 2026 election. Polls by media organisations do not in themselves alter party rules or trigger internal procedures, but they can reflect and amplify public and internal party sentiment ahead of formal challenges.
Labour officials have emphasised procedural safeguards and the thresholds required to trigger leadership contests, while saying the party remains focused on policy and campaigning. Starmer and senior ministers continue to prepare for the general election, with party strategists watching opinion trends and internal morale as they finalise their campaign approach.
For now, the question of whether Starmer will still lead the country after next May remains contested both in public opinion polls and within the parliamentary Labour Party, with formal removal contingent on the party's internal rules and the actions of its MPs.
