Prime Ministers

Who was Ramsay Macdonald?  When was Asquith?  What (and why) was Bonar Law?  Whenever I hear one of these names I wish I knew more about British politics of the past hundred years.

I was about to say that I don't care so much about the Nineteenth Century...  but now I sense a creeping uncertainty about Gladstone, Disraeli, Palmerston, Peel and Melbourne.

Still, for my own benefit, I've just drawn up a list of Twentieth Century prime ministers.
