The government’s efforts to get changes to the backstop have run into a brick wall in Brussels. The EU thinks, with justification, that MPs won’t allow no deal and so feels under no pressure to make significant concessions. As I write in The Sun this morning, one minister fully briefed on the negotiations says ‘we’re at what the hell do we do time’

But without a change to the backstop, Theresa May’s deal is going down to another heavy defeat on Tuesday.
