Terminological inexactitude

The Second Shadow Cabinet of Edward Heath was created after the Conservative Party lost the February 1974 general election.
 It was led by the Leader of the Conservative Party Edward Heath and featured prominent Conservative politicians both past and future.
 Included was Heath’s successor Margaret Thatcher, the future Home Secretary William Whitelaw, and two future Foreign Secretaries, Lord Carrington and Francis Pym.
 For the first time in history, a leadership election was held in 1975 for the Conservative Party whilst the position was not vacant.
 Margaret Thatcher challenged Heath, with whom the majority of the party was dissatisfied because of repeated losses at elections.
 She won, becoming the first female leader of a major political party in Britain.
Lyng's Cabinet governed Norway between 28 August 1963 and 25 September 1963.
 It was the first in 28 years not to be led by the Norwegian Labour Party.
 It was a centre-right coalition government of the Conservative Party, Centre Party, Christian Democratic Party and Liberal Party led by John Lyng of the Conservative Party.
 It had fifteen members, of which five were from the Conservative Party, four were from the Centre Party, three were from the Christian Democratic Party and three were from the Liberal Party.
 Karen Grønn-Hagen was the cabinet's only female member.
The Conservative Party Review (2016) is a set of internal reforms within the Conservative Party of the United Kingdom.
 It was the brainchild of Conservative Party Chairman, Andrew Feldman, Baron Feldman of Elstree, and has been regarded as the widest-reaching and most radical internal reforms in the Conservative Party since the 1940s.
The Federation of Conservative Students (FCS) was the student organisation of the British Conservative Party from the late 1940s to 1986.
 It was created to act as a bridge between the student movement and the Conservative Party.
 In its final years it became known colloquially as "Maggie's Militant Tendency", in reference to then Prime Minister Margaret Thatcher and to Militant, an entryist group active in the Labour Party at the time.
 The FCS was then broken up by the Chairman of the Conservative Party, Norman Tebbit, after one of its members had accused previous former Prime Minister Harold Macmillan of war crimes in extraditing Cossacks to the Soviet Union.
 The FCS was replaced by the Conservative Collegiate Forum.
Alfred Edwards (23 March 1888 – 17 June 1958) was a British politician who served for fifteen years as a Member of Parliament (MP).
 His origins were as a company director in the foundry industry in Middlesbrough, which led him into conflict with the Labour Party when it proposed to nationalise the iron and steel industries; profoundly unable to support the party, he crossed the floor and became an active Conservative Party supporter.
The Social Christian Conservative Party (Spanish: "Partido Conservador Social Cristiano" , PCSC) was a centrist political party in Chile, founded in 1949 as the Conservative Party split in two factions.
 For electoral purposes, one of the factions was named the Social Christian Conservative Party (the other being called the Traditionalist Conservative Party).
 Some of the Social Christian Conservatives later returned to form in together with the 'Traditionals' the United Conservative Party (1953), whereas others participated in the with the National Falange from 1955 to 1957.
 In July 1957 the Social Christian Conservative Party merged with the Chilean National Falange to form the Christian Democratic Party of Chile.
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.

 However, the 2017 snap election on Thursday 8 June resulted in a hung parliament, and the Conservatives lost their parliamentary majority.
