is never used, although it, too, is sometimes used by foreign dignitaries and news sources. 10 Downing Street, in London, has been the official place of residence of the prime minister since 1732; they are entitled to use its staff and facilities, including extensive offices. Chequers, a country house in Buckinghamshire, gifted to the government in 1917, may be used as a country retreat for the prime minister. Retirement honours Upon retirement, it is customary for the sovereign to grant a prime minister some honour or dignity. The honour bestowed is commonly, but not invariably, membership of the UK's most senior order of chivalry, the Order of the Garter. The practice of creating a retired prime minister a Knight of the Garter (KG) has been fairly prevalent since the mid-nineteenth century. Upon the retirement of a prime minister who is Scottish, it is likely that the primarily Scottish honour of Knight of the Thistle (KT) will be used instead of the Order of the Garter, which is generally regarded as an English honour. Historically it has also been common to grant prime ministers a peerage upon retirement from the Commons, elevating the individual to the Lords. Formerly, the peerage bestowed was usually an earldom. The last such creation was for Harold Macmillan, who resigned in 1963. Unusually, he became Earl of Stockton only in 1984, over twenty years after leaving office. Macmillan's successors, Alec Douglas-Home, Harold Wilson, James Callaghan and Margaret Thatcher, all accepted life peerages (although Douglas-Home had previously disclaimed his hereditary title as Earl of Home). Edward Heath did not accept a peerage of any kind and nor have any of the prime ministers to retire since 1990, although Heath in 1992, John Major in 2005 and Tony Blair in 2022 were later appointed as Knights of the Garter, the latter had previously disclosed that he did not want honours bestowed for himself or future prime ministers. The most recent former prime minister to die was Margaret Thatcher (1979–1990) on 8 April 2013. Her death meant that for the first time since 1955 (the year in which the Earldom of Attlee was created, subsequent to the death of Earl Baldwin in 1947) the membership of the House of Lords included no former prime minister, a situation which remains the case as of 2022.
