10 Downing Street, London, UK

10 Downing Street, Office of The Rt Hon Liz Truss Prime Minister also known colloquially in the United Kingdom simply as Number 10, is 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.

Introduction – by Sir Anthony Seldon

10 Downing Street, the locale of British prime ministers since 1735, vies with the White House as being the most important political building anywhere in the world in the modern era. Behind its black door have been taken the most important decisions affecting Britain for the last 275 years. In the 20th century alone, the First and Second World Wars were directed from within it, as were the key decisions about the end of the empire, the building of the British nuclear bomb, the handling of economic crises from the Great Depression in 1929 to the great recession, and the building up of the welfare state.

Some of the most famous political figures of modern history have lived and worked in Number 10, including Robert Walpole, Pitt the Younger, Benjamin Disraeli, William Gladstone, David Lloyd George, Winston Churchill and Margaret Thatcher. Number 10 has 3 overlapping functions. It is the official residence of the British Prime Minister: it is their office, and it is also the place where the Prime Minister entertains guests from Her Majesty The Queen to presidents of the United States and other world leaders. The Prime Minister hosts countless receptions and events for a whole range of British and overseas guests, with charitable receptions high up the list.

The building is much larger than it appears from its frontage. The hall with the chequered floor immediately behind the front door lets on to a warren of rooms and staircases. The house in Downing Street was joined to a more spacious and elegant building behind it in the early 18th century. Number 10 has also spread itself out to the left of the front door, and has taken over much of 12 Downing Street, which is accessed by a corridor that runs through 11 Downing Street – the official residence of the Chancellor of the Exchequer.

Prime Minister Elizabeth Truss is the Member of Parliament for South West Norfolk. Appointed Minister for Women and Equalities. Born in Leeds to left-wing parents, Liz broke the mould and started her career as an economist and accountant with a Conservative membership card. She was elected as a councillor in Greenwich in 2006, and then as MP for South West Norfolk in 2010. She was one of the first MPs of her intake to enter Government in 2012.

She travelled to Japan, South Korea, Brazil and Chile to see how countries around the globe are turbocharging economic growth, controlling public finances and delivering world-class public services.
