Will Andy Burnham formally announce a bid for Labour Party leader before 1 July 2026?

Market resolves to YES if Andy Burnham makes a public, unambiguous announcement that he is standing (or intends to stand) for leader of the UK Labour Party before 1 July 2026. Media speculation, bookmaker odds, or private conversations do not count. A written statement, press conference, or official social media post from Burnham or his authorised spokesperson is sufficient. Resignation from his GM Mayor role is not required for YES.
