Keir Starmer has resigned as UK prime minister, making his successor the seventh prime minister in a decade — a genuine reflection of British political instability. The post uses humor to highlight the extraordinary turnover at 10 Downing Street, contrasting it with Larry the cat's steady 10-year tenure. What's unmentioned: Starmer served less than two years before resigning, part of a pattern where recent UK leaders have increasingly struggled to sustain public support or party backing.
