"It is possible, though hard, to forge a United Kingdom made up of many ethnicities. Leaders like Mr Cameron are right to try to insist on common standards and better rules, rather than to despair. But whatever it is, and however well it turns out, it cannot be England. Perhaps when I am very old, my grandchildren will ask me what England was. It will be a hard question to answer, but I think I shall tell them that it seemed like a good idea while it lasted, and that it lasted for about 1,000 years."
