My Lords, I very strongly support these amendments. I stress that we are locking ourselves into leaving the European Union on a specific timetable which is coming up very soon, given that nothing much will happen in the summer and that it will take some time to get ratified whatever interim withdrawal agreement is agreed by this October. We are up against a very short deadline. The reasons why this is a mistake include that the Government lost a great deal of time unnecessarily in negotiations within government and the Cabinet, and with their own right wing, before they got down to the detail of the negotiations to which they are now committed.
As the Government negotiate, we are discovering a substantial shift of tone. The Prime Minister’s Mansion House speech made it clear that she wants to stay associated with a very large number of European Union agencies. There is talk of a large and ambitious new security treaty between the UK and the European Union, and Commons committees and committees of this House have said that it is absolutely in Britain’s interests that we remain associated with Europol, data sharing and a whole host of other things which only EU membership gives us.
