Cameron, David

Prime Minister in Great Britain from May 11, 2010. Leader of the Conservative party in the United Kingdom. He won the elections 6 May 2010 with 306 seats to his party. Labour lost 91 seats, down to 258. The Libereal Democrats won votes but lost seats, down to 57.

Majority in Westminster requires 326 seats.

Cameron had promised a referendum on the Lisbon Treaty if he would win the elections before the Treaty was ratified by all 27 member states.

The Lisbon Treaty entered into force 1 December 2009. The British Conservatives have therefore chosen a different strategy.
