European Union Bill

The noble Lord said that he would not say anything about the potentially damaging effect on our negotiating position or negotiating leverage if this Bill is passed into law. I was disappointed to hear him say that, because there are few people in the world who have greater experience of negotiation in Brussels than he has. Does he agree that, when you are negotiating in any context in life, you have a certain leverage if at the end of the day, when you are persuaded and you have done a deal, you can actually deliver? However, if it is known in advance that you cannot deliver because you need a referendum to deliver—the Government are obviously not going to have a referendum on some subject of tertiary importance—does he agree with me that you will not really have any negotiating leverage at all, because no one will make concessions to you in the expectation of getting agreement if you cannot give agreement in the first place?
