Prime Minister's office

10 Downing Street is the official residence and office of the Prime Minister of the United Kingdom.

Under the Prime Minister's predecessor
When Cornelius Fudge, the Minister for Magic, used the Floo Network to introduce himself to the Prime Minister's precessor, he thought Fudge was an attempt to sabotage him, and tried to throw the wizard out one of the windows.

Under the Prime Minister
The Prime Minister met Cornelius Fudge here for the first time. Despite Fudge's claim that they would probably never meet again after their first introduction, due to all the Dark activities of the wizarding world, this claim was contradicted, much to the Prime Minister's discomfort.

Fudge met the Prime Minister again in 1993 to inform him of Sirius Black's breakout from Azkaban. Convinced Black would be caught quickly, Fudge alerted the Prime Minister of the situation, and asked that the Muggles keep an eye out for Black, as well.

The next year, Fudge met again with the Muggle Prime Minister, to inform him of the magical creatures the Ministry of Magic was bringing into the country for the Triwizard Tournament, which was to be held at Hogwarts School of Witchcraft and Wizardry that year.

In 1996, the Prime Minister was under pressure after the collapse of the Brockdale Bridge, and a hurricane that had devastated parts of the South-West of England. He was informed by Cornelius Fudge, who was sacked from his position, that Lord Voldemort and his Death Eaters were responsible for both events. He also learned that his new secretary, Kingsley Shacklebolt was a highly skilled Auror, and met the new Minister, Rufus Scrimgeour.
