Question: What position did the person who The Sun supported in 1974 hold?

full_context: Document 1: The Sun (United Kingdom): Politically, The Sun in the early Murdoch years, remained nominally Labour. It supported the Labour Party led by Harold Wilson in the 1970 General Election, with the headline "Why It Must Be Labour" but by February 1974 it was calling for a vote for the Conservative Party led by Edward Heath while suggesting that it might support a Labour Party led by James Callaghan or Roy Jenkins. In the October election an editorial asserted: "ALL our instincts are left rather than right and we would vote for any able politician who would describe himself as a Social Democrat."
Document 2: Prime Minister of the United Kingdom: The Prime Minister of the United Kingdom is the head of Her Majesty's Government in the United Kingdom. The Prime Minister (informally abbreviated to PM) and Cabinet (consisting of all the most senior ministers, most of whom are government department heads) are collectively accountable for their policies and actions to the Monarch, to Parliament, to their political party and ultimately to the electorate. The office is one of the Great Offices of State. The current holder of the office, Theresa May, leader of the Conservative Party, was appointed by the Queen on 13 July 2016.
Document 3: Elizabeth II: The absence of a formal mechanism within the Conservative Party for choosing a leader meant that, following Eden's resignation, it fell to the Queen to decide whom to commission to form a government. Eden recommended that she consult Lord Salisbury, the Lord President of the Council. Lord Salisbury and Lord Kilmuir, the Lord Chancellor, consulted the British Cabinet, Winston Churchill, and the Chairman of the backbench 1922 Committee, resulting in the Queen appointing their recommended candidate: Harold Macmillan.
Document 4: The Sun (United Kingdom): The Sun, during the Miners' strike of 1984–85, supported the police and the Thatcher government against the striking NUM miners, and in particular the union's president, Arthur Scargill. On 23 May 1984, The Sun prepared a front page with the headline "Mine Führer" and a photograph of Scargill with his arm in the air, a pose which made him look as though he was giving a Nazi salute. The print workers at The Sun refused to print it. The Sun strongly supported the April 1986 bombing of Libya by the US, which was launched from British bases. Several civilians were killed during the bombing. Their leader was "Right Ron, Right Maggie". That year, Labour MP Clare Short attempted in vain to persuade Parliament to outlaw the pictures on Page Three and gained opprobrium from the newspaper for her stand.
Document 5: The Sun (United Kingdom): Despite its initial opposition to the closures, until 1997, the newspaper repeatedly called for the implementation of further Thatcherite policies, such as Royal Mail privatisation,[verification needed] and social security cutbacks, with leaders such as "Peter Lilley is right, we can't carry on like this",[verification needed] The paper showed hostility to the EU and approval of public spending cuts, tax cuts, and promotion of right-wing ministers to the cabinet, with leaders such as "More of the Redwood, not Deadwood".
Document 6: The Sun (United Kingdom): The Sun switched support to the Labour party on 18 March 1997, six weeks before the General Election victory which saw the New Labour leader Tony Blair become Prime Minister with a large parliamentary majority, despite the paper having attacked Blair and New Labour up to a month earlier. Its front page headline read THE SUN BACKS BLAIR and its front page editorial made clear that while it still opposed some New Labour policies, such as the Minimum Wage and Devolution, it believed Blair to be "the breath of fresh air this great country needs". John Major's Conservatives, it said, were "tired, divided and rudderless". Blair, who had radically altered his party's image and policies, noting the influence the paper could have over its readers' political thinking, had courted it (and Murdoch) for some time by granting exclusive interviews and writing columns.
Document 7: The Sun (United Kingdom): Politically, the paper's stance was less clear under Prime Minister Gordon Brown who succeeded Blair in June 2007. Its editorials were critical of many of Brown's policies and often more supportive of those of Conservative leader David Cameron. Rupert Murdoch, head of The Sun's parent company News Corporation, speaking at a 2007 meeting with the House of Lords Select Committee on Communications, which was investigating media ownership and the news, said that he acts as a "traditional proprietor". This means he exercises editorial control on major issues such as which political party to back in a general election or which policy to adopt on Europe.
Document 8: Leader of the Conservative Party (UK): Leader of the Conservative Party Incumbent Theresa May since 11 July 2016 Inaugural holder Robert Peel (de facto) Bonar Law (de jure) Formation 1834 (de facto) 1922 (de jure)
Document 9: Brown ministry: Gordon Brown formed the Brown ministry after being invited by Queen Elizabeth II to begin a new government following the resignation of the previous Prime Minister of the United Kingdom, Tony Blair, on 27 June 2007. He took office as Prime Minister, a title he would hold until his resignation on 11 May 2010. In his inaugural cabinet, Brown appointed the United Kingdom's first female Home Secretary, Jacqui Smith.
Document 10: Dudley Smith: Smith served as a junior minister for the British Army and Employment during the Edward Heath government of 1970 to 1974.
Document 11: Heath ministry: Edward Heath of the Conservative Party formed the Heath ministry and was appointed Prime Minister of the United Kingdom by Queen Elizabeth II on 19 June 1970, following the 18 June general election. Heath's ministry ended after the February 1974 general election, which produced a hung parliament, leading to the formation of a minority government by Harold Wilson of the Labour Party.
Document 12: The Sun (United Kingdom): These years included what was called "spectacularly malicious coverage" of the Labour Party by The Sun and other newspapers. During the general election of 1983 The Sun ran a front page featuring an unflattering photograph of Michael Foot, then aged almost 70, claiming he was unfit to be Prime Minister on grounds of his age, appearance and policies, alongside the headline "Do You Really Want This Old Fool To Run Britain?" A year later, in 1984, The Sun made clear its enthusiastic support for the re-election of Ronald Reagan as president in the USA. Reagan was two weeks off his 74th birthday when he started his second term, in January 1985.
Document 13: The Sun (United Kingdom): The Sun remained loyal to Thatcher right up to her resignation in November 1990, despite the party's fall in popularity over the previous year following the introduction of the Poll tax (officially known as the Community Charge). This change to the way local government is funded was vociferously supported by the newspaper, despite widespread opposition, (some from Conservative MPs), which is seen as having contributed to Thatcher's own downfall. The tax was quickly repealed by her successor John Major, whom The Sun initially supported enthusiastically, believing he was a radical Thatcherite – despite the economy having entered recession at this time.
Document 14: Blair ministry: Tony Blair originally formed the Blair ministry in May 1997 after being invited by Queen Elizabeth II to form a new government following the resignation of the previous Prime Minister, John Major of the Conservative Party, as a result of the Labour Party's landslide victory at the 1997 general election. He would serve as the Prime Minister for three successive ministries and parliamentary terms until his resignation on 27 June 2007. His Cabinet was reshuffled for each new parliament along with a few minor changes during each term.
Document 15: Government of the United Kingdom: The current prime minister is Theresa May, who took office on 13 July 2016. She is the leader of the Conservative Party, which won a majority of seats in the House of Commons in the general election on 7 May 2015, when David Cameron was the party leader; although at the last general election she failed to secure a majority government. Prior to this, Cameron and the Conservatives led a coalition from 2010 to 2015 with the Liberal Democrats, in which Cameron was prime minister.
