The PM asked for an extension of article 50 to 30 June.
The PM got a two-tier extension.
22 May if Parliament passes the withdrawal agreement
12 April if it doesn’t.
Much talk of ‘indicative votes’ in Parliament next week. If this leads to a consensus on the type of Brexit to be achieved, this could only affect the political declaration as to the negotiation of the UK’s future relationship with the EU. The withdrawal agreement, backstop and all, cannot be changed and if it is not passed the UK leaves the EU on 12 April, subject to amendment by Statutory Instrument next week of “exit day” in the EU Withdrawal Act 2018, unless a further extension is granted. This would almost certainly require the UK to hold elections for the European Parliament on 23 May.
