We are going back into the past and I think that the results of the Second World War were a little more complicated than that. The European Union was initially created as a body against the eastern bloc. I am not going to go into the causes of war—the noble Baroness, Lady Deech, gave us examples —but the European Union has not always been very cohesive in its defence policy. The world has changed. Cyber attacks are now dangerous, so we need to look outwards a little more.
The point is that people voted to leave in a democratic vote and we should respect their decision. I know that along with my husband, some noble Lords voted to remain, but we should not undercut the negotiating powers—some are saying that Boris Johnson has no negotiating powers—of a Prime Minister. He has to have the support of parliamentarians. His job is to deliver what the people wanted.
