Zeuhl...can't agree I'm afraid.
If Blair had said that he enjoyed being PM so much that he was going to stay in Number 10 until he died, and that Euan will be PM after him, we would all have stormed Downing Street, with lighted brands and pitchforks, rather in the fashion that the local villagers did in those old Hammer horror films, when Dracula was ensconced in his mountain top castle.
So I am not sure why, in 2013, we are still prepared to put up with an unelected head of state, who is entitled to sit on the throne because some ancient ancestor 100's of years ago fought a battle somewhere in a field in England and won.
What is right about an elected PM and Government, but so very wrong about an elected Head of State ? Why do you support choice in everything but not at Buck House ? You don't like the idea President Blair or Boris. Well, neither do I, but if the people elect them, so be it. Its called democracy.
I am a republican, but if Liz wants to put herself forward as a candidate for President, than I shall almost certainly vote for her, as she is very experienced and nobody's fool.
But under a Monarchy, we were just a minibus crash away from having Queen Fergie....much scarier than President Boris !
