Document 7: 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 8: 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 10: The Sun (United Kingdom): Critics stated that both The Sun and Lord Kilbracken cherry-picked the results from one specific study while ignoring other data reports on HIV infection and not just AIDS infection, which the critics viewed as unethical politicisation of a medical issue. Lord Kilbracken himself criticised The Sun's editorial and the headline of its news story; he stated that while he thought that gay people were more at risk of developing AIDS it was still wrong to imply that no one else could catch the disease. The Press Council condemned The Sun for committing what it called a "gross distortion". The Sun later ran an apology, which they ran on Page 28. Journalist David Randall argued in the textbook The Universal Journalist that The Sun's story was one of the worst cases of journalistic malpractice in recent history, putting its own readers in harm's way.
Document 11: 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 13: 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 14: 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 15: 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."
