Tony Blair was Prime Minister of the United Kingdom of Great Britain and Northern Ireland and Leader of the Labour Party between 1997-2007. He served as the Member of Parliament (MP) for Sedgefield from the 1983 general election until his resignation from the House of Commons in June 2007.
Blair welcomed the Simpsons at the London Heathrow Airport terminal, along with other overseas arrivals. Homer tries to bribe him with an American dollar to get him to leave them alone, but he steals it instead. Lisa suggests that Blair gives the family a personal tour of the country, but he declines, flying away on a jetpack to greet a Dutch couple at Gate 23.
