I am surprised by the hon. Lady. I have known her a very long time and I know she is extremely assiduous and very intelligent, so she will have read article 50 and observed that it contains an express provision for agreement between the EU and in this case the UK to delay the date which would otherwise pertain. In fact, there are also rules for what is required on the EU side by way of unanimity to permit that to occur. There is no question, therefore, of the Government ever having asserted that they could not change the article 50 date; they have always said and known that it is possible to change it. The question, as my right hon. and learned Friend the Member for Beaconsfield (Mr Grieve) said a moment ago, is how we make sure that UK law marches in step with whatever happens under the article 50 process.
