My Lords, if I may intervene in this debate, I think it is still important that what used to be the custom and convention be clarified on paper. This is for a very simple reason. While I agree with the noble Lord, Lord Grocott, that it is inconceivable
that a monarch could refuse the request of a Prime Minister, there is always a possibility. For example, in India, which has a constitution based very much on British lines, the president is elected by the Parliament, and very often he or she is a partisan person and would be unable to refuse the Prime Minister under any circumstances. We have to reserve the power of the monarch. If what the Prime Minister is saying does not smell good when he or she is asking for a dissolution, the monarch should have the power to say no.
