My hon. Friend is obviously ready to transfer to the upper tier of new authority being created in Europe virtually all the major powers of self government, and he justifies that on the grounds that there they will be taken at a more appropriate level. He cites the environment. If we are serious about the environment, we should look for a solution not at the western European half-continental level, but at the global level. Does my hon. Friend advocate our becoming part of a world government, part of an expanded United Nations? What would he say, for example, to the proposition that we should be better defended by a huge European army or a combined European defence force? Would he be happy to hand over our powers of self defence to such a body? Would he not prefer such arrangements to come under NATO rather than being taken away from us to be decided by a supranational law-making body?
