Does my right hon. and learned Friend agree that article 31 of the Vienna convention makes it perfectly clear that this protocol does have legal force, is binding and is of equal status to the treaty? Does he also agree that substantial, legally binding changes have been delivered, and that it is wrong to read just one paragraph of his legal advice—one has to read each paragraph of it? When it comes to paragraph 17 of his advice, my right hon. and learned Friend makes it clear that this is a substantial change in the level of risk.
