Very important breaking news. Which is that trade unions, in their TULO meeting with Jeremy Corbyn, have tonight endorsed the Labour leader’s position that in a general election Labour should campaign for a referendum that would have a “credible leave option and remain” on the ballot paper.

The reason this matters is that those senior members of the shadow cabinet, such as Keir Starmer, Emily Thornberry, John McDonnell and Tom Watson, who want Labour to adopt an unambiguous remain position have been defeated.
