Tony Blair became the first Labour Prime Minister ever to win a full consecutive second term when he was re-elected on June 7, 2001. To date, Labour has a 166-seat majority in the House of Commons. At the 2003 Labour Party conference, Prime Minister Blair announced that he intends to seek a third term. The Conservative (Tory) Party and Liberal-Democrats (LibDems) form the major opposition parties. The main British parties support a strong transatlantic link but have become increasingly absorbed by European issues as Britain's economic and political ties to the continent grow in the post-Cold War world. Prime Minister Blair has promised that the United Kingdom will play a leading role in Europe even as it maintains its strong bilateral relationship with the United States. Britain's relationship with Europe, in particular its potential participation in the single European currency, the euro, is a subject of considerable political discussion in the United Kingdom. Chancellor of the Exchequer Gordon Brown has stipulated that a public referendum on adopting the euro will occur only after five economic tests are met. Most expect that a referendum will not take place prior to the next general election.
