This year will see the UK General Election, where it is widely expected that the British Labour Party will be ousted by the Tories from No. 10 after thirteen years of Government.
The election bloodletting started a while ago, although now it is really getting nasty.
With that in mind, I suggest that you add to your saved Twitter searches the UK General Election 2010 hashtag. (Note: you can also follow it using this tag.)
