Nick Clegg

"Nick, it's Dave. I'm supposed to be opening some primary school in Wales; can't be arsed. Nip down there and stand in for me would you? There's a biscuit in it for you."

Leader of the Liberal Democrats and rumoured to be a clone of Tony Blair, only with a much better looking wife (still a lawyer though).

Currently doing Prime Minister impressions thanks to David Cameron not getting quite enough seats to form a 100% Tory govt and giving him a job as his stand in.

Nobody had a clue who he was until the televised leaders' debates, then everyone caught Blairitis again, but in a much less virulent form. So much less virulent in fact that, despite a surge in Lib Dem support, they actually lost seats in the 2010 election.
