SIR - I was with your editorial all the way on the benefits of EU migration, until you said 'the die is cast' on Brexit.

The case put forward by the Leave campaign in 2016 continues to unravel in the face of the facts, including the facts you highlight about migration. It has become clear that the people must be given the opportunity to decide whether the deal (if any) that the Government is able to negotiate on Brexit is preferable to the advantages of staying within the European Union.
