Like four of the five previous UK prime ministers, Keir Starmer was forced to resign, rather than being voted out. Last time — Liz Truss in 2022 — it was the bond market that did the forcing. Gilt investors hated her fiscally expansive mini-Budget, and she was toast. With Starmer, no one can convincingly explain why, with a huge majority in Parliament, he had to go. It will be debated by historians for decades. The City was clearly not the culprit.
