The Commons motion last night to reject a so called no deal or WTO exit does not change the law. That says we leave on 29 March.
Those who wish to delay Brexit need to persuade the government to go to the EU to negotiate a delay, and then to legislate for a delay. The EU so far is rightly asking what would the delay be for and how long would it be. They point out they are not willing to renegotiate the Withdrawal Agreement. They had indicated they might give a short delay to implement the Agreement if passed, or a bit longer delay to hold a second referendum. The government and a good number of Labour MPs remain rightly against any such second Peoples vote.
The forces of delay have not coalesced around a period of delay with a purpose the EU would accept. Mrs May still wishes to give her deal another airing in the Commons. This story has no definitive ending before the 29 March.
