Government of Wales Bill

May I point out—the hon. Gentleman may already be aware—that that is exactly what the amendments passed in the House of Lords say? They do not seek to knock out the power to make the retrospective legislation; they seek to insert that very form of words. The Minister says that that presents difficulties. The hon. Member for Montgomeryshire (Lembit Öpik) may agree with me that in those circumstances the solution is for the Minister to find a form of words that meets the spirit of what has been said, but does not have those difficulties attached to it.
