The hon. Gentleman has made a powerful case. In fact, he has unwittingly made a powerful case for a written constitution, which would prevent that from happening. What we have, however, is a convention, and, like it or not, conventions mean what the Executive say—rather than, as we are finding now in relation to going to war in Syria, creeping something through the House and reinventing the convention. Unfortunately, the Prime Minister of the day would probably find, in giving way, that the Deputy would be appointed from within the coalition or from within the individual party. The only way of putting a stop to that is to have clarity, so that everyone watching at home has the rule book, the boxing rules, as it were. I am not referring to the fighters in the ring, but there should be a framework that we can all understand, and I am afraid that that is not the case.
Ultimately, even under the current legislation, it would be possible to dissolve Parliament if a vote expressing a lack of confidence in the existing Government were carried by two thirds. After 14 days, there would be a general election. However, those are extraordinary circumstances. We are trying to build a democracy in which everyone out there knows the rules.
