Context paragraphs:
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.

Mark Clarke (politician): Mark Clarke, born in June 1977, is a former UK Conservative Party parliamentary candidate that has been referred to as the "Tatler Tory", who is also former Director of the Young Britons' Foundation, former Chairman of Conservative Future, and ex-Director of the since-disbanded "Road Trip" electioneering organisation that bussed Conservative Party activists to marginal seats during the 2015 general election.  Clarke was suspended from the Party on 24 September 2015, following the suicide of Conservative activist Elliott Alston Raymond Johnson who had named Clarke as having bullied him.  A series of serious accusations subsequently appeared in several national newspapers about Clarke’s alleged misconduct and in November 2015 he was finally expelled and banned for life from representing or joining the Conservative Party again.  His alleged misconduct within the Conservative Party led to national newspaper coverage about the extent to which senior figures in the Party knew about complaints regarding his actions, coverage that subsequently led to the resignation of Grant Shapps, a government minister.

Stephen Crabb: Stephen Crabb{'1': ", '2': ", '3': ", '4': "} (born 20 January 1973) is a British Conservative Party politician.  He has been the Member of Parliament for Preseli Pembrokeshire since the 2005 general election and was Secretary of State for Work and Pensions from March 2016 until July 2016, when Prime Minister David Cameron resigned and Theresa May took over as Prime Minister and Leader of the Conservative Party.  He has previously been a government whip, a junior minister for Wales and the Secretary of State for Wales.

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.

Colin Craig: Colin Craig (born 8 January 1968) is a New Zealand businessman who was the founding leader of the Conservative Party of New Zealand.  Craig is a millionaire who owns companies that manage high-rise buildings.  His current company manages about $1.3 billion of assets.  He is against same-sex marriage, foreign ownership of land and housing and "anti-smacking" legislation.  In June 2015, Craig resigned as leader of the Conservative Party following allegations of inappropriate behaviour surrounding the party's former press secretary Rachel MacGregor and tensions with the party's governing board.  Craig has since admitted to inappropriate conduct with MacGregor but has denied charges of sexual harassment.  On 27 June, Colin Craig was formally suspended from the Conservative Party.  Since then, his suspension has been invalidated which would enable Craig to contest the Conservative Party's leadership.  On 16 November 2015, Craig announced that he would not be contesting the Conservative Party leadership in lieu of a police investigation against him over his Party's spending during the 2014 general election.

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.

United Kingdom general election, 1837: The 1837 United Kingdom general election was triggered by the death of King William IV and produced the first parliament of the reign of his successor, Queen Victoria.

Later life of Winston Churchill: The later life of Winston Churchill documents the life of the British statesman from the end of World War II and his second term as Prime Minister of the United Kingdom, until his subsequent death and funeral in 1965.  After the end of the war Churchill had to step down as Prime Minister of the United Kingdom because the Conservative Party lost the 1945 election.  For six years he was to serve as the Leader of the Opposition.  During these years Churchill continued to influence world affairs; in 1946 he gave his Iron Curtain speech which spoke of the expansionist policies of the USSR and the creation of the Eastern Bloc; Churchill also argued strongly for British independence from the European Coal and Steel Community (which he saw as a Franco-German project as Britain still had an empire).  In the General Election of 1951 Labour was defeated and Churchill became Prime Minister for a second time.  Churchill continued to lead Britain but was to suffer increasingly from health problems.  Aware that he was slowing down both physically and mentally he resigned from the Cabinet in 1955.  However he continued to sit as an MP for Woodford until he retired from politics in 1964.  Churchill died on 24 January 1965 and was granted the honour of a state funeral.  He was buried in his family plot in St Martin's Church, Bladon near to where he was born at Blenheim Palace.

He played a central role in the creation of the modern Conservative Party, defining its policies and its broad outreach.  Disraeli is remembered for his influential voice in world affairs, his political battles with the Liberal Party leader William Ewart Gladstone, and his one-nation conservatism or "Tory democracy".  He made the Conservatives the party most identified with the glory and power of the British Empire.  He is the only UK Prime Minister to have been of Jewish birth.
