Question: The Prime Minister of the United Kingdom from 1957 to 1963 led the Conservative Government of the United Kingdom with which other person?

full_context: Document 1: Conservative Party (UK): The Conservative Party, officially the Conservative and Unionist Party, is a centre-right political party in the United Kingdom. It is currently the governing party, having been so since the 2010 general election, where a coalition government with the Liberal Democrats was formed. In 2015, the Conservatives led by David Cameron won a surprise majority and formed the first Conservative majority government since 1992. However, the 2017 snap election on Thursday 8 June resulted in a hung parliament, and the Conservatives lost their parliamentary majority. They are reliant on the support of a Northern Irish political party, the Democratic Unionist Party (DUP), in order to command a majority in the House of Commons through a confidence-and-supply deal. The party leader, Theresa May, has served as both Leader of the Conservative Party and Prime Minister since 13 July 2016. It is the largest party in local government with 9,237 councillors. The Conservative Party is one of the two major contemporary political parties in the United Kingdom, the other being its modern rival, the Labour Party. The Conservative Party's platform involves support for free market capitalism, free enterprise, fiscal conservatism, a strong national defence, deregulation, and restrictions on trade unions.

Document 14: List of Prime Ministers of the United Kingdom: The Prime Minister of the United Kingdom is the head of the Government of the United Kingdom, and chairs Cabinet meetings. There is no specific date when the office of Prime Minister first appeared, as the role was not created but rather evolved over a period of time. The term was used in the House of Commons in 1805 and it was certainly in parliamentary use by the 1880s, and in 1905 the post of Prime Minister was officially given recognition in the order of precedence. Modern historians generally consider Sir Robert Walpole, who led the government of Great Britain from 1721 to 1742, as the first Prime Minister. Walpole is also the longest-serving Prime Minister by this definition. However, Sir Henry Campbell-Bannerman was the first Prime Minister and Margaret Thatcher the longest-serving Prime Minister to have been officially referred to as such.
