Theresa May’s cabinet committee on Brexit met yesterday and considered three new papers, I’ve heard. A draft of one was reported to include that controversial £66bn cost of reverting WTO rules.

But there were two others as well, on free movement and interestingly the customs union, which was discussed.

Liam Fox has suggested Britain will leave the customs union, and Raoul Ruparel - the new adviser to David Davis who was the co-director at Open Europe- has said Britain will have to leave, arguing “that ship has sailed”.

But Treasury ministers are pushing back internally saying there has to be a conversation about cost of an exit, and clearly the issue remains on the table.
