Downing Street’s revolving door keeps spinning as Starmer faces pressure

Britain’s prime ministerial turnover has accelerated since the 2016 Brexit referendum, and Keir Starmer, who took office in July 2024, is now at risk of becoming the seventh leader to fall in a decade. Once a symbol of stability, 10 Downing Street has seen six prime ministers pass through since Brexit, with Starmer now facing open questions about whether he can survive in office.

As of May 2026, Starmer’s approval rating has dropped to 19%, a historic low. Labour’s heavy defeat in local elections to Nigel Farage’s Reform party prompted more than 80 Labour MPs to call for his resignation, fearing he could cost the party power in 2029. Potential challengers inside Labour, including Manchester Mayor Andy Burnham, are already positioning themselves.

The article says Brexit is the central cause of the instability, along with repeated failures by British leaders to make it work. David Cameron resigned after losing the referendum he called, Theresa May collapsed under the effort to implement Brexit, Boris Johnson quit after scandals including Partygate, Liz Truss lasted only 45 days after her economic plan shook markets, and Rishi Sunak failed to tackle the cost of living after 14 years of Conservative rule.

The problem is described as structural as well as personal. Britain’s system lets a governing party replace its leader without a general election, which has made political upheaval seem routine. At the same time, the old Labour-Conservative duopoly has fragmented into a five-party system, with Farage’s right-wing populists pulling support from both main parties. The article says Brexit has cost Britain 4% to 8% of GDP, reduced business investment, and helped drive a 20% rise in living costs over four years. More Britons now favor rejoining the European Union, but any future leader will still face the wider national reckoning over Britain’s direction.
