With a ceremonial head of state and an elected government surely the British system is the same as most in the developed world?
I may be wrong but in the current EU I think only France has an executive head of state. In the wider 'west', only the USA does.
Yes in principle but the current situation makes it hard to say yes in practice.
I do though - the thought of a superannuated politician being head of state is too awful to contemplate. President Nigel anyone?
