New prime minister would be 7th since the 2016 Brexit vote

U.K. PM Keir Starmer is set to resign on June 23, 2026, amid pressures regarding his leadership position.

In his resignation speech, Starmer pledged to ensure an orderly transition of power and said he would remain in office until a new Labour leader is elected.

If Starmer leaves office this year, Britain will get its seventh prime minister in a decade.
