Leader of the Opposition (United Kingdom) in the context of "Margaret Thatcher"

David William Donald Cameron, Baron Cameron of Chipping Norton (born 9 October 1966), is a British politician who served as Prime Minister of the United Kingdom from 2010 to 2016. Until 2015, he led the first coalition government in the UK since 1945 and resigned after a referendum supported the country's leaving the European Union. After his premiership, he served as Foreign Secretary in the government of prime minister Rishi Sunak from 2023 to 2024. Cameron was Leader of the Conservative Party from 2005 to 2016 and served as Leader of the Opposition from 2005 to 2010. He was Member of Parliament (MP) for Witney from 2001 to 2016, and has been a member of the House of Lords since November 2023. Cameron identifies as a one-nation conservative and has been associated with both economically liberal and socially liberal policies.

Born in London to an upper-middle-class family, Cameron was educated at Eton College and Brasenose College, Oxford. After becoming an MP in 2001, he served in the opposition Shadow Cabinet under Conservative leader Michael Howard, and succeeded Howard in 2005. Following the 2010 general election, negotiations led to Cameron becoming prime minister as the head of a coalition government with the Liberal Democrats.

Herbert Henry Asquith, 1st Earl of Oxford and Asquith (/ˈæskwɪθ/ ASS-kwith; 12 September 1852 – 15 February 1928), generally known as H. H. Asquith, was a British statesman and Liberal politician who was Prime Minister of the United Kingdom from 1908 to 1916. He was the last prime minister from the Liberal Party to command a majority government, and the most recent Liberal to have served as Leader of the Opposition. He played a major role in the design and passage of major liberal legislation and a reduction of the power of the House of Lords. In August 1914 Asquith took the United Kingdom of Great Britain and Ireland and the British Empire into the First World War. During 1915 his government was vigorously attacked for a shortage of munitions and the failure of the Gallipoli Campaign. He formed a coalition government with other parties, but failed to satisfy critics, was forced to resign in December 1916 and never regained power.

After attending Balliol College, Oxford, he became a successful barrister. In 1886 he was the Liberal candidate for East Fife, a seat he held for over thirty years. In 1892 he was appointed Home Secretary in William Ewart Gladstone's fourth ministry, remaining in the post until the Liberals lost the 1895 election. In the decade of opposition that followed, Asquith became a major figure in the party, and when the Liberals regained power under Sir Henry Campbell-Bannerman in 1905, Asquith was named Chancellor of the Exchequer. In 1908 Asquith succeeded him as prime minister. The Liberals were determined to advance their reform agenda. An impediment to this was the House of Lords, which rejected the People's Budget of 1909. Meanwhile, the South Africa Act 1909 passed. Asquith called an election for January 1910, and the Liberals won, though they were reduced to a minority government. After another general election in December 1910, he gained passage of the Parliament Act 1911, allowing a bill three times passed by the Commons in consecutive sessions to be enacted regardless of the Lords. Asquith was less successful in dealing with Irish Home Rule. Repeated crises led to gun running and violence, verging on civil war.

Sir Keir Rodney Starmer (born 2 September 1962) is a British politician and lawyer who has served as Prime Minister of the United Kingdom since 2024 and as Leader of the Labour Party since 2020. He previously served as Leader of the Opposition from 2020 to 2024. He has been Member of Parliament (MP) for Holborn and St Pancras since 2015, and was Director of Public Prosecutions from 2008 to 2013.

Born in Southwark, London, and raised in Surrey, Starmer was politically active as a teenager, and graduated with a Bachelor of Laws degree from the University of Leeds in 1985 and received a postgraduate Bachelor of Civil Law degree from St Edmund Hall, Oxford, in 1986. After being called to the Bar, Starmer worked predominantly in criminal defence, specialising in human rights. He served as a human rights adviser to the Northern Ireland Policing Board, taking silk as a Queen's Counsel in 2002. During his tenure as Director of Public Prosecutions and head of the Crown Prosecution Service, he handled a number of major cases, including the Stephen Lawrence murder case. In the 2014 New Year Honours, he was appointed a Knight Commander of the Order of the Bath (KCB) for services to law and criminal justice.

Rishi Sunak (born 12 May 1980) is a British politician and former investment banker who served as Prime Minister of the United Kingdom and Leader of the Conservative Party from 2022 to 2024. Following his defeat to Keir Starmer's Labour Party in the 2024 general election, he became Leader of the Opposition, serving in this role from July to November 2024. He previously held two Cabinet positions under Boris Johnson, latterly as Chancellor of the Exchequer from 2020 to 2022. Sunak has been Member of Parliament (MP) for Richmond and Northallerton, previously Richmond (Yorks), since 2015.

Sunak was born in Southampton to parents of Indian descent who immigrated to Britain from East Africa in the 1960s. He was educated at Winchester College, studied philosophy, politics and economics at Lincoln College, Oxford, and earned a Master of Business Administration from Stanford University in California as a Fulbright Scholar. During his time at Oxford University, Sunak joined the Conservatives. After graduating, Sunak worked for Goldman Sachs and later as a partner at two hedge fund firms. Sunak was elected to the House of Commons at the 2015 general election. As a backbencher, Sunak supported the successful campaign for Brexit in the 2016 European Union membership referendum. Sunak was appointed to the junior ministerial position of Parliamentary Under-Secretary of State for Local Government by Theresa May in 2018, and was appointed to the cabinet-attending role of Chief Secretary to the Treasury by Johnson in 2019.

Michael Howard, Baron Howard of Lympne CH PC KC (born Michael Hecht; 7 July 1941) is a British politician who was Leader of the Conservative Party and Leader of the Opposition from November 2003 to December 2005. He previously held cabinet positions in the governments of Margaret Thatcher and John Major, including Secretary of State for Employment, Secretary of State for the Environment and Home Secretary.

Howard was born in Swansea to a Jewish family, his father from Romania and his mother from Wales. He studied at Peterhouse, Cambridge, following which he joined the Young Conservatives. In 1964, he was called to the bar and became a Queen's Counsel in 1982. He first became a Member of Parliament at the 1983 general election, representing the constituency of Folkestone and Hythe. This quickly led to his promotion and Howard became Minister for Local Government in 1987. Under the premiership of John Major, he served as Secretary of State for Employment (1990–1992), Secretary of State for the Environment (1992–1993) and home secretary (1993–1997).

David Cameron was Leader of the Conservative Party and Leader of the Opposition from his election as Leader on 6 December 2005 until he became Prime Minister on 11 May 2010. His tenure as opposition leader was characterised by opposition to the Great Recession from 2007 to 2009, and his relative youth and inexperience before becoming leader invited satirical comparison with Tony Blair. Cameron sought to rebrand the Conservatives, embracing an increasingly socially liberal position, and introducing the "A-List" to increase the number of female and minority ethnic Conservative MPs.

Cameron had four Shadow Cabinets during his tenure as opposition leader. His Shadow Cabinet appointments included MPs associated with the various wings of the party. Former leader William Hague was appointed to the Foreign Affairs brief, while both George Osborne and David Davis were retained, as Shadow Chancellor of the Exchequer and Shadow Home Secretary respectively. Hague, assisted by Davis, stood in for Cameron during his paternity leave in February 2006. In June 2008, Davis announced his intention to resign as an MP, and was immediately replaced as Shadow Home Secretary by Dominic Grieve; Davis' surprise move was seen as a challenge to the changes introduced under Cameron's leadership.

Philosophy, politics and economics, or politics, philosophy and economics (PPE), is an interdisciplinary undergraduate or postgraduate degree which combines study from three disciplines. The first institution to offer degrees in PPE was the University of Oxford in the 1920s. This particular course has produced a significant number of notable graduates such as Aung San Suu Kyi, Burmese politician and former State Counsellor of Myanmar, Nobel Peace Prize winner; Princess Haya bint Hussein, daughter of the late King Hussein of Jordan; Christopher Hitchens, the British–American author and journalist; Will Self, British author and journalist; Oscar-winning writer and director Florian Henckel von Donnersmarck; Michael Dummett, Gareth Evans, Philippa Foot, Christopher Peacocke, Gilbert Ryle, Paul Snowdon, and Peter Strawson, philosophers; Harold Wilson, Edward Heath, David Cameron, Liz Truss and Rishi Sunak, Prime Ministers of the United Kingdom; Hugh Gaitskell, Michael Foot, William Hague and Ed Miliband, former Leaders of the Opposition; former Prime Ministers of Pakistan Benazir Bhutto and Imran Khan; and Malcolm Fraser, Bob Hawke and Tony Abbott, former Prime Ministers of Australia; and Malala Yousafzai, Nobel Peace Prize winner.

In the 1980s, the University of York went on to establish its own PPE degree based upon the Oxford model; King's College London, the University of Warwick, the University of Manchester, and other British universities later followed. According to the BBC, the Oxford PPE "dominate[s] public life" in the UK. It is now offered at several other leading colleges and universities around the world. More recently Warwick University and King's College added a new degree under the name of PPL (Politics, Philosophy and Law) with the aim to bring an alternative to the more classical PPE degrees.

Sir Anthony Charles Lynton Blair (born 6 May 1953) is a British politician who served as Prime Minister of the United Kingdom from 1997 to 2007 and Leader of the Labour Party from 1994 to 2007. He was Leader of the Opposition from 1994 to 1997 and held various shadow cabinet posts from 1987 to 1994. Blair was Member of Parliament (MP) for Sedgefield from 1983 to 2007, and was special envoy of the Quartet on the Middle East from 2007 to 2015. He is the second-longest-serving prime minister in post-war British history after Margaret Thatcher, the longest-serving Labour politician to have held the office, and the first and only person to date to lead the party to three consecutive general election victories. Blair founded the Tony Blair Institute for Global Change in 2016, and currently serves as its Executive Chairman.

Blair attended the independent school Fettes College, studied law at St John's College, Oxford, and qualified as a barrister. He became involved in the Labour Party and was elected to the House of Commons in 1983 for the Sedgefield constituency in County Durham. As a backbencher, Blair supported moving the party to the political centre of British politics. He was appointed to Neil Kinnock's shadow cabinet in 1988 and was appointed shadow home secretary by John Smith in 1992. Following Smith's death in 1994, Blair won a leadership election to succeed him. As leader, Blair began a historic rebranding of the party, which became known as "New Labour". Blair became the youngest prime minister of the 20th century after his party won a landslide victory of 418 seats (the largest in its history) in the 1997 general election, bringing an end to 18 years in the opposition. It was the first victory for the Labour Party in nearly 23 years, the last one being in October 1974.
