Dan Jarvis Named UK Defence Secretary After Loyalist Healey's Surprise Resignation

—Dan Jarvis has been appointed UK Defence Secretary following the sudden resignation of John Healey, who had been one of Keir Starmer's most trusted cabinet loyalists. Healey's departure was described as a destabilizing blow to the prime minister at a moment of already difficult domestic politics. Analysts questioned whether Jarvis, though respected, has the political weight to hold the brief as the UK navigates major decisions on defence spending and Ukraine policy. Starmer now faces pressure to stabilize his cabinet while managing a growing list of policy challenges.
