After months of rumours, denials of those rumours, more rumours and then an obligatory “away day”, Labour has today unveiled its new policy on Brexit.

At a speech in Coventry (which backed Brexit by 55 per cent to 45 per cent) Jeremy Corbyn will announce his party’s support of “a” customs union with the European Union after Brexit.

On one level the move is smart politics: it puts clear water between Labour and the government and allows the party to side with Tory rebels when the issue comes to a vote in parliament later next year.

With about a dozen or more Conservatives almost certain to vote against the government on its customs union policy, there is a clear prospect of defeat for Theresa May.
