Business of the House

My hon. Friend regularly asks me questions. It is fair to say that his scientific knowledge exceeds mine and I therefore have to make a stab at an answer. However, I feel on stronger ground on this subject, which has fascinated some hon. Members for a long time. I was once a member of a commission that examined the various arrangements that could be introduced for proportional representation and, if I had an hour or two, I could probably go through them all. However, there is a clear debate to be held about the principle. It goes on and the Government take it seriously.
