n a fast-moving and unpredictable political environment, it is far from clear how the Brexit process will unfold in the coming days and weeks. But here is the rough timetable events which Westminster insiders are expecting:

Monday 2 September: Boris Johnson called an unexpected meeting of his cabinet to agree that any parliamentary motion which ties his hands in negotiations with Brussels should be regarded as an issue of confidence in his handling of Brexit talks. This makes it easier for any rebels to be stripped of the Tory whip and barred from standing for the party in an election, but also heightens speculation that a snap election may be on the way. Immediately after the meeting, Johnson was addressing Conservative MPs at a No 10 garden party.
