Notes: 10 Downing Street, also known colloquially in the United Kingdom as Number 10, is (along with the adjoining Cabinet Office at 70 Whitehall) the headquarters of the Government of the United Kingdom and the official residence and office of the First Lord of the Treasury, a post which, for much of the 18th and 19th centuries and invariably since 1905, has been held by the Prime Minister of the United Kingdom. The term “10 Downing Street”, or just “Downing Street”, is also used as a metonym for the Prime Minister’s office. (Wikipedia)
