Woosh are you sure!. My reading of the ECJ judgement allowed the UK to unilaterally repeal or extend upto thecutoff date.no, that's not correct. We need an extension which has to be agreed by all 27 member states of the EU27 but we can withdrawl A50 unilaterally at any time.
Imagine TM asks Juncker and Tusk to extend A50.
TM concedes a new GE in April.
GE in May.
JC does not win enough seats so he forms a coalition with the SNP and LibDems.
Guess what, the SNP and LibDems then ask JC to withdraw A50.
Impossible scenario?
