 Tony Blair recorded his part for the episode in April 2003 , in ten minutes at Downing Street . Blair was sent the script early on in the writing process , and it took eight months of negotiation between Fox and Blair 's director of communications Alastair Campbell before Blair could guest star . In the original script , Blair was supposed to welcome the Simpsons to the United Kingdom " with a garland of ' genuine Newcastle coal ' and hand [ Marge ] a complimentary Corgi " , but Campbell had them changed , as Blair " made it very clear that he was only interested in doing the show if he could promote tourism in Britain " . The show 's staff did not know whether Blair would actually record his lines until showrunner Al Jean and his wife were in London promoting the 300th episode of The Simpsons . They received a call stating : " If you go over to Downing Street tomorrow and can promise to get the recording done in 15 minutes , then the Prime Minister will do it " . Jean was " so nervous , it was ridiculous " when he met Blair , an event he has cited as " one of the most fantastic moments of his life " . Blair was the top choice to guest star in the episode , but the staff did not think they had a chance to get him to appear . Blair is the only head of government to guest star in the show , with Rudy Giuliani ( who played himself in the episode " Stop or My Dog Will Shoot " ) the only other politician to guest star .
