LONDON (Reuters) - British trade minister Liam Fox said on Monday that Britain might not leave the European Union if Prime Minister Theresa May’s deal is not approved by parliament, triggering a democratic and constitutional crisis.

“We either leave the European Union with a deal...or we leave with no deal which is possible but I think parliament makes that unlikely, or we don’t leave at all which I think would produce a democratic as well as a constitutional crisis,” Fox told BBC radio.
