Fixed-term Parliaments Bill

My Lords, I listened with great attention to the Minister a moment ago and I think that I detected an anxiety on his part that the royal prerogative on the dissolution of Parliament would somehow be thrown into confusion. Her Majesty the Queen graciously places her prerogative at the disposal of Parliament every time the question arises. She always has and always will. I hope that the Minister will elaborate on the anxieties if indeed I am right to detect them in what he said, but I cannot see the problem about the Queen's personal prerogative of dissolution being revived on a vote of the House of Commons if the amendment of the noble Lord, Lord Butler, is passed. There is no constitutional dilemma at all here. Perhaps he has better advice than I have and perhaps he could elaborate in a moment or two.
