European Union Bill

My Lords, that makes the point that I wished to make about the character of the alliances, even in an area that is as sensitive for us as defence. I suspect that most people would conclude that our membership of those alliances has been absolutely fundamental to the security of our country and would not wish to see them shaken. Were there to be some absolutely massive change in the architecture of defence, it might be so substantive as to require a mechanism that is contained in an amendment and has been in past undertakings that we have made. However, it would be a fairly extraordinary event that looked as though it were even more significant than the arrangements that we have under the provisions of the NATO treaty.
