Note that the focus is now about Watson v Corbyn, not Owen Smith v Corbyn. And last night in his final message before close-of-poll, the leadership challenger sounded like a man who knew the game was up. His statement, claiming he’d at least put some new policies on the table and started a debate, sounded like a valedictory. His conscious uncoupling with Corbyn started weeks ago. The leadership ballot closes at midday, but there won’t be ‘closure’, as the Americans put it, for some MPs.
