Wes Streeting secures 81 MP backers, triggers Labour contest

Wes Streeting, the UK health secretary, won backing from 81 Labour MPs, meeting the 20% nomination threshold under Labour Party rules to trigger a formal leadership contest against Prime Minister Keir Starmer. Labour holds 403 MPs in Parliament, so 20% equals 81 endorsements.

The reported endorsements followed Labour’s losses in local elections on May 8, 2026. Under party procedures, meeting the nomination threshold would allow Streeting to be put forward as a formal candidate once the count is verified by party officials.

Prediction markets adjusted their odds after the report. The market for “Starmer out by June 30, 2026” rose to 46.5% from 40% a week earlier. The market for “Starmer out by December 31, 2026” increased to 77.5% from 68% over the same period.

The next step is formal confirmation of nominations by Labour’s party machinery. If the nominations are ratified, Labour’s rules set a timetable and a ballot process to select a new leader; the party has not published a schedule.

Key figures to watch include Morgan McSweeney and Deputy Leader Angela Rayner. Keir Starmer’s office had not issued a statement at the time of the report. Observers are awaiting any formal declarations of candidacy from other senior MPs and any official notification from the party that a contest has been opened.
