Brexit: Catch up with EU referendum fallout
Already the parties are at odds with how to proceed -- Cameron is insisting that the terms of the separation be struck before the country invokes Article 50 of the Lisbon Treaty, which will officially put the separation process in motion. But European leaders want the article triggered immediately, saying the divorce terms should be agreed after.

Brexit political turmoil: A swathe of senior opposition Labour Party MPs resigned from Labour's shadow cabinet and a prominent member was sacked in the wake of the referendum. There are calls for new leadership but party leader Jeremy Corbyn won't resign.
