The backstop has been essentially replaced by a complete shutdown that will allow Northern Ireland to be aligned with the EU for at least four years from the end of the transition period. A change can only occur if it is voted on by the Stormont Assembly. Parliament will have to approve any future relations agreement.

Ursula von der Leyen warned Johnson not to violate international law and said that the implementation of the withdrawal agreement by Britain was a « precondition for any future partnership ».
