Background: Robin Cook was born in the County Hospital, Bellshill, Scotland, the only son of Peter and Christina Cook (nee Lynch). His father was a Chemistry teacher who grew up in Fraserburgh, and his grandfather was a miner before being blacklisted for being involved in a strike. Cook was educated at Aberdeen Grammar School and, from 1960, the Royal High School in Edinburgh. At first, Cook intended to become a Church of Scotland minister, but lost his faith as he discovered politics.
Context: Cook became known as a brilliant parliamentary debater, and rose through the party ranks, becoming a frontbench spokesman in 1980, and reaching the Shadow Cabinet in June 1983, as spokesperson on European affairs. He was campaign manager for Neil Kinnock's successful 1983 bid to become leader of the Labour Party. A year later he was made party campaign co-ordinator but in October 1986 Cook was surprisingly voted out of the shadow cabinet. He was re-elected in July 1987 and in October 1988 elected to Labour's National Executive Committee. He was one of the key figures in the modernisation of the Labour Party under Kinnock. He was Shadow Health Secretary (1987-92) and Shadow Trade Secretary (1992-94), before taking on foreign affairs in 1994, the post he would become most identified with (Shadow Foreign Secretary 1994-97, Foreign Secretary 1997-2001).  In 1994, following the death of John Smith, he ruled himself out of contention for the Labour leadership, apparently on the grounds that he was "insufficiently attractive" to be an election winner, although two close family bereavements in the week in which the decision had to be made may have contributed.  On 26 February 1996, following the publication of the Scott Report into the 'Arms-to-Iraq' affair, he made a speech in response to the then President of the Board of Trade Ian Lang in which he said "this is not just a Government which does not know how to accept blame; it is a Government which knows no shame". His parliamentary performance on the occasion of the publication of the five-volume, 2,000-page Scott Report--which he claimed he was given just two hours to read before the relevant debate, thus giving him three seconds to read every page--was widely praised on both sides of the House as one of the best performances the Commons had seen in years, and one of Cook's finest hours. The government won the vote by a majority of one.  As Joint Chairman (alongside Liberal Democrat MP Robert Maclennan) of the Labour-Liberal Democrat Joint Consultative Committee on Constitutional Reform, Cook brokered the 'Cook-Maclennan Agreement' that laid the basis for the fundamental reshaping of the British constitution outlined in Labour's 1997 General Election manifesto. This led to legislation for major reforms including Scottish and Welsh devolution, the Human Rights Act and removing the majority of hereditary peers from the House of Lords. Other measures have not been enacted so far, such as further House of Lords reform. On 5 May 2011 the United Kingdom held a referendum on replacing the first-past-the-post voting system with the Alternative Vote method. On 6 May it was announced that the proposed move to the AV voting system had been rejected by a margin of 67.9% to 32.1%.  With the election of a Labour government led by Tony Blair at the 1997 general election, Cook became Foreign Secretary. He was believed to have coveted the job of Chancellor of the Exchequer, but that job was reportedly promised by Tony Blair to Gordon Brown. He announced, to much scepticism, his intention to add "an ethical dimension" to foreign policy.  His term as Foreign Secretary was marked by British interventions in Kosovo and Sierra Leone. Both of these were controversial, the former because it was not sanctioned by the UN Security Council, and the latter because of allegations that the British company Sandline International had supplied arms to supporters of the deposed president in contravention of a United Nations embargo. Cook was also embarrassed when his apparent offer to mediate in the dispute between India and Pakistan over Kashmir was rebuffed. The ethical dimension of his policies was subject to inevitable scrutiny, leading to criticism at times.  Cook was responsible for achieving the agreement between Britain and Iran that ended the Iranian death threat against author Salman Rushdie, allowing both nations to normalize diplomatic relations. He is also credited with having helped resolve the eight-year impasse over the Pan Am Flight 103 bombing trial by getting Libya to agree to hand over the two accused (Megrahi and Fhimah) in 1999, for trial in the Netherlands according to Scots law.  In March 1998, a diplomatic rift ensued with Israel when Israeli Prime Minister Benjamin Netanyahu cancelled a dinner with Cook, while Cook was visiting Israel and had demonstrated opposition to the expansion of Israeli settlements.  Although a republican, he and the Queen were on excellent terms, due to their mutual interest in horses.  After the 2001 general election he was moved, against his wishes, from the Foreign Office to be Leader of the House of Commons. This was widely seen as a demotion--although it is a Cabinet post, it is substantially less prestigious than the Foreign Office--and Cook nearly turned it down. In the event he accepted, and looking on the bright side welcomed the chance to spend more time on his favourite stage. According to The Observer, it was Blair's fears over political battles within the Cabinet over Europe, and especially the euro, which saw him demote the pro-European Cook.  As Leader of the House he was responsible for reforming the hours and practices of the Commons and for leading the debate on reform of the House of Lords. He also spoke for the Government during the controversy surrounding the membership of Commons Select Committees which arose in 2001, where Government whips were accused of pushing aside the outspoken committee chairs Gwyneth Dunwoody and Donald Anderson. He was President of the Party of European Socialists from May 2001 to April 2004.  In early 2003, during a television appearance on BBC's debating series Question Time, he was inadvertently referred to as "Robin Cock" by David Dimbleby. Cook responded with good humour with "Yes, David Bumblebee", and Dimbleby apologised twice on air for his slip. The episode also saw Cook in the uncomfortable position of defending the Government's stance over the impending invasion of Iraq, weeks before his resignation over the issue.  He documented his time as Leader of the House of Commons in a widely acclaimed memoir The Point of Departure, which discussed in diary form his efforts to reform the House of Lords and to persuade his ministerial colleagues, including Tony Blair, to distance the Labour Government from the foreign policy of the Bush administration. The former political editor of Channel 4 News, Elinor Goodman called the book 'the best insight yet into the workings of the Blair cabinet', the former editor of The Observer, Will Hutton, called it "the political book of the year--a lucid and compelling insider's account of the two years that define the Blair Prime Ministership".
