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

Context paragraphs:
Clement Attlee: Clement Richard Attlee, 1st Earl Attlee, {'1': ", '2': ", '3': ", '4': "} (3 January 1883 – 8 October 1967) was a British Labour politician who served as Prime Minister of the United Kingdom from 1945 to 1951 and Leader of the Labour Party from 1935 to 1955.  In 1940, Attlee took Labour into the wartime coalition government and served under Winston Churchill, becoming the first person to hold the office of Deputy Prime Minister of the United Kingdom.  He went on to lead the Labour Party to an unexpected landslide victory at the 1945 general election; forming the first Labour majority government, and a mandate to implement its postwar reforms.  The 12.0% national swing from the Conservatives to Labour was unprecedented at that time and remains the largest ever achieved by any party at a general election in British electoral history.  He was re-elected with a narrow majority at the 1950 general election.  In the following year, Attlee called a snap general election, hoping to increase his parliamentary majority.  However, he was narrowly defeated by the Conservatives under the leadership of Winston Churchill; despite winning the most votes of any political party in any general election in British political history until the Conservative Party's fourth consecutive victory in 1992.  Attlee remains the longest-ever serving Leader of the Labour Party.

Swedish governmental line of succession: The Swedish constitution of 1974 allows the Prime Minister of Sweden to appoint one of the Ministers in the cabinet as Deputy Prime Minister ("biträdande statsminister", also unofficially known as "vice statsminister", "Vice Prime Minister"), in case the Prime Minister for some reason is prevented from performing his or her duties.  However, if a Deputy Prime Minister has not been appointed, the Minister in the cabinet who has served the longest time (and if there are several with equal experience the one who is oldest) takes over as head of government.  Note that the person acting as Prime Minister does not do so on a permanent basis: if a Prime Minister dies, resigns or loses a vote of confidence in the Riksdag, the Speaker of the Riksdag will then confer with the parties of the Riksdag and propose a new Prime Minister, who must be tolerated by a majority of the Riksdag.  If the Prime Minister has resigned or lost a vote of confidence, he or she will remain the head of a government "ad interim" until the new Prime Minister assumes his or her office.  The only case where the governmental line of succession becomes relevant is when the Prime Minister dies (upon which the person next in the line of succession serves as the head of a government "ad interim") or when the Prime Minister is on leave or for any other reason incapable of serving, but still remains in office.  This might be compared to the Presidential line of succession in the United States, where the person next in line assumes the Presidency throughout the remainder of the term if the President dies, resigns or is impeached.

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.

Conservative Party (UK) leadership election, 1997: The 1997 Conservative Party leadership election was triggered in the British Conservative Party when John Major resigned on 2 May 1997, following his party's defeat at the 1997 general election, which ended 18 years of Conservative Government of the United Kingdom.  Major had been Conservative leader and Prime Minister since November 1990.

Conservative government, 1957–1964: The Conservative government of the United Kingdom that began in 1957 and ended in 1964 consisted of three ministries: the first Macmillan ministry, second Macmillan ministry, and then the Douglas-Home ministry.  They were led by Harold Macmillan and Sir Alec Douglas-Home, who were appointed respectively by Queen Elizabeth II.

UK miners' strike (1984–85): The miners strike of 1984–85 was a major industrial action to shut down the British coal industry in an attempt to prevent colliery closures.  It was led by Arthur Scargill of the National Union of Mineworkers (NUM) against the National Coal Board (NCB), a government agency.  Opposition to the strike was led by the Conservative government of Prime Minister Margaret Thatcher, who called Scargill "the enemy within."  The NUM was divided over the action and many mineworkers, especially in the English Midlands, worked through the dispute.  Few major trade unions supported the NUM, primarily because of the absence of a vote at national level.  Violent confrontations between flying pickets and police characterised the year-long strike, which ended in a decisive victory for the Conservative government and led to the closure of most of Britain's collieries.  It was "the most bitter industrial dispute in British history."  At its height, the strike involved 142,000 mineworkers.  The number of days of work lost to the strike was over 26,000,000, making it the largest since the 1926 general strike.

Harold Macmillan: Maurice Harold Macmillan, 1st Earl of Stockton, {'1': ", '2': ", '3': ", '4': "} (10 February 1894 – 29 December 1986) was a British statesman of the Conservative Party who served as Prime Minister of the United Kingdom from 1957 to 1963.  Nicknamed "Supermac", he was known for his pragmatism, wit and unflappability.

Prime Minister of Northern Ireland: The Prime Minister of Northern Ireland was the head of the Government of Northern Ireland between 1921 and 1972.  No such office was provided for in the Government of Ireland Act 1920, however the Lord Lieutenant, as with Governors-General in other Westminster Systems such as in Canada, chose to appoint someone to head the executive even though no such post existed in statute law.  The office-holder assumed the title "Prime Minister" to draw parallels with the Prime Minister of the United Kingdom.  On the advice of the new Prime Minister, the Lord Lieutenant then created the "Department of the Prime Minister".  The office of Prime Minister of Northern Ireland was abolished in 1972, along with the contemporary government, when direct rule of Northern Ireland was transferred to London.

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.

British-American Parliamentary Group: The British-American Parliamentary Group is a all-party parliamentary group consisting of members of the Parliament of the United Kingdom.  “The objects of the British-American Parliamentary Group are to promote friendly relations and mutual understanding between Members of both Houses of Parliament of the United Kingdom and Members of both Houses of Congress of the United States of America; to discuss problems common to the United Kingdom and the United States; to exchange courtesies and to provide opportunities for discussion with Senators, members of the House of Representatives, and other distinguished citizens of the United States; and to arrange for the exchange of visits and information between legislators of both countries.”  Its co-presidents are the Speaker of the House of Commons and the Lord Speaker, among the vice presidents are former Speakers of the House of Commons, one former prime minister, the current deputy prime minister, former leaders of the opposition, and former foreign secretaries.  The chairman is the prime minister.  There are currently over 600 members from both the Labour and Conservative parties.
