Is the resignation of the Defence Secretary a sign of instability in Keir Starmer's government?

John Healey resigned as Defence Secretary on 12 June 2026, citing insufficient funding for the armed forces amid rising threats from Russia and NATO commitments. The UK ranks 31st out of 32 NATO members in meeting rearmament targets. Healey's departure followed months of disputes over budget increases, with the government exploring cuts elsewhere to address the shortfall.
