Gordon Brown -- very impressive resume. He certainly is no idot and has lots of political experience.
Prior to this he served as the Chancellor of the Exchequer under Tony Blair from 1997 to 2007, becoming the United Kingdom's longest serving Chancellor since Nicholas Vansittart in the early 19th century. He has a PhD in history from the University of Edinburgh[2][3], and, as Prime Minister, he also holds the positions of First Lord of the Treasury and the Minister for the Civil Service. He has been a Member of Parliament since 1983; firstly for Dunfermline East and now for Kirkcaldy and Cowdenbeath.
Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
