If I had known that my right hon. Friend was such a keen smoker, I would not have recruited her to the Conservative party at the tender age of 18 when we were at university.

I have always taken a free-choice approach to health matters, and as shadow Children’s Minister I had to lead on both the tobacco advertising ban and the public smoking ban. We were wrong to oppose them. Who would now think it remotely normal for people to be able to smoke around us in restaurants and other public places? Does my right hon. Friend not agree that in a few years’ time this measure will seem just the same as banning smoking in public places, and people will ask why we did not do it earlier?
