I like it! I think the Queen should step up and take over the Government. Then I think she ought to put Prince Phillip the Royal Consort over the Army. He's been waiting his whole life to kick... some... ass.
Unless there have been any more substantial changes in British law that I would be caught unawares on, it allows the Crown to take over the government during a state of war. Hasn't been done since Britain's involvment in the Crimean war, but they had a Parliament back then too (dittos for Revolution and 1812)...
