Broadly, the argument about full access and control of our borders is an argument that the Prime Minister has already made in the last few weeks,
so I do not think I need to elaborate on it. However, let us understand something about this—sometimes, we seem to be arguing over which end of the egg we open first. The argument between us is where the dividing line is on what we tell Parliament about. The hon. and learned Gentleman recognised in terms, I think, that we could not give every detail to Parliament and that, despite his letter, we could not give a blow-by-blow account—that we could not have Parliament dictate how we dealt with the trade-offs, the terms and so on. [Interruption.] Despite the noise to his right, it is fairly plain that that is what the criterion is; that is where the problem is.
Let us be clear how this applies. If someone tells their opposite number in a negotiation exactly what their top priority is, that will make that top priority extremely expensive. Ordinary people, in their ordinary lives, probably do one big transaction themselves, and that is the purchase of a house. If someone went to buy a house, and they looked at only one house, told the owner that they were in love with that house and made a bid for it, I suspect the price would go up.
