there are those who would like to see a certain pensioner relocated somewhere smaller. however like it or not this certain pensioner is still head of state and at this time, there is no credible political party campaigning on a manifesto of an elected head of state, so the UK will continue to be represented on the world stage by a monarch.
it really wouldn't show the country in a very good light if foreign dignitaries were received by the UK head of state at a council house in Slough, would it?
