In the early part of the decade, King George II offered 10 Downing Street to the First Lord of the Treasury, Robert Walpole, agreeing to Walpole's suggestion that the property be made available to all future heads of government; Walpole himself was in effect the Prime Minister of the United Kingdom, although that term was not yet in use. Mr Chicken, the last private tenant of the property, moved to another house in Downing Street, and the property was refurbished and extended, incorporating stables and another house to produce one official residence. Walpole moved into 10 Downing Street in 1735. (PROSE: The Time Traveller's Almanac ^[+]Loading...["The Time Traveller's Almanac (reference book)"])
