European Union (Notification of Withdrawal) Bill

Despite the right hon. Gentleman’s certainty about irrevocability, the person who drafted the clause, Lord Kerr, thinks that notification is revocable. The right hon. and learned Member for Beaconsfield (Mr Grieve), the former Attorney General, who is sitting to the right hon. Gentleman’s right, is not absolutely sure but does not agree with him, and the Brexit Minister does not know. Does this not remind us of a certain question in European history, where of those who knew the answer one was mad, one was dead and the other had forgotten? Is this the basis on which he wants to take us over the cliff edge?
