Ministry of Magic
The Ministry of Magic is the government of the Magical community of Britain in J. K. Rowling's Harry Potter series. First mentioned in Harry Potter and the Philosopher's Stone, the Ministry makes its first proper appearance in Harry Potter and the Order of the Phoenix. Throughout the books, it is generally depicted as either corrupt, incompetent, or both, with its high officials blind to actual events and dangers. It reaches a nadir of corruption before being effectively taken over by Lord Voldemort.
Composition and status
Connection to "Muggle" world
Each new Muggle Prime Minister receives a visit from the Minister for Magic, who informs him or her that the wizarding world exists. He explains that he will contact the Prime Minister only in circumstances in which the events of the wizard world may affect Muggles. For example, the Minister has to inform the Prime Minister if dangerous magical artifacts or animals are to be brought into Britain.
The Ministry keeps in touch with the British Prime Minister via a wizard's portrait in the Prime Minister's office at 10 Downing Street. The portrait, which cannot be removed from the wall (because of a Permanent Sticking Charm in place), notifies the Prime Minister of the Minister for Magic's arrival and, after they have been notified, the Minister for Magic appears in their office via the fireplace which has specifically been hooked up to the floo network.[HP6] The Ministers for Magic who appear in the Harry Potter series, such as Cornelius Fudge and Rufus Scrimgeour, tend to act in a somewhat patronising manner towards the Muggle Prime Minister.
