The unions have been very vocal in their opposition to Brexit right from the off. Because they know full well the impact on the jobs and incomes of their members. A pity that the labour leadership, such as it is, decided to sit the referendum out, then sit in silence since.
As the John Harris article Daz linked points out, the de facto opposition to Brexit isn’t coming from a naval-gazing labour party, happy to coalesce in this catastrophe, but from Anna Soubry, Nicky Morgan, Ken Clark and Dominic Grieve within the Tory’s own ranks. And the actions of Labour MP’s like Kate Hoey and Frank Field in helping the Tory’s get Brexit bills through parliament are absolutely inexcusable.
As this disaster unfolds, and the full implications of Brexit for the working classes become apparent, the dereliction of duty by Corbyn and his anti-EU acolytes won’t be forgotten
