Fixed-term Parliaments Bill

I am a little puzzled as to why the hon. Gentleman comes to the conclusion that this needs to be codified in any way. Our history demonstrates quite openly that this House comes to such a resolution by the processes of the House. When Mr Chamberlain won the famous Norway debate, he recognised that there was no confidence in him personally. These matters are eventually decided by the House and by the judgment of individuals. Surely that is the better way of doing it.
