British political biographer Anthony Seldon, who has chronicled at least eight prime ministers over the past decade, says the rapid turnover of leaders has made his work increasingly difficult. Once able to study long-serving premiers in depth, Seldon now finds himself racing to keep up with constant political upheaval. The latest turbulence surrounds Labour Prime Minister Keir Starmer, whose leadership is under threat after severe local election losses in England, Scotland, and Wales. Seldon fears the UK could see its sixth prime minister in seven years by August, when his biography of Rishi Sunak is due for release.

The instability reflects deeper national challenges. The UK has struggled to recover from the 2008 financial crisis, with stagnant wages, post-pandemic inflation, and Brexit-related economic decline. Political fragmentation has also eroded the traditional two-party dominance, as smaller parties gain ground across the nations. Analysts and academics cited in the report describe Starmer as principled but lacking charisma and a clear narrative, while some Labour MPs are rallying around Manchester Mayor Andy Burnham as a potential successor.

A by-election in Makerfield will test Labour’s strength and could determine whether the party stabilizes or faces deeper crisis.
