What we really need by the way is something like the Prime Minister’s question time in the House of Commons. I have never seen anyone as good as Prime Minister Blair at the art of ducking. Even President Clinton. Admittedly, the back benchers are very rude, but a good Prime Minister can take it and the whole episode is great entertainment.
