Is Britain getting a new prime minister?

UK Prime Minister Keir Starmer’s premiership is under severe threat after his approval rating plunged to -51%, down from +9 immediately after Labour’s 2024 election victory. The party’s support in polls has fallen to 19-20%, trailing behind both the Conservatives and Reform UK, raising fears of a crushing defeat in a potential general election. Labour MPs are increasingly discussing a leadership change, with Starmer’s tenure becoming the most unstable since the party took power in 1924. The instability stems from Starmer’s rapid decline in public trust, with his approval rating turning negative within weeks of taking office. Labour’s electoral dominance—winning 411 of 650 parliamentary seats in 2024—has eroded as the party struggles with economic concerns and internal divisions. Key figures like Deputy Prime Minister Angela Rayner resigned in September 2025 over a tax scandal, while Chancellor Rachel Reeves’ reputation for fiscal responsibility has been damaged. Andy Burnham, the Mayor of Greater Manchester since 2017, has positioned himself as the most viable alternative to Starmer. A former Labour Cabinet minister (2007–10), Burnham left Parliament to lead Greater Manchester, overseeing a region of 3 million people—the largest outside London. Polls suggest he is more popular with Labour members and could offer a fresh direction, though his path to leadership remains uncertain. Labour’s history shows leadership changes can happen abruptly, with four such shifts occurring between 2016 and 2022. However, no UK prime minister has ever been forced out of office against their will. With Starmer’s approval ratings at historic lows and the party’s future in doubt, a leadership contest could reshape British politics within months.
