The Co-operative Commonwealth Federation (Ontario) – The Farmer-Labor Party of Ontario, or more commonly known as the Ontario CCF, was a democratic socialist political party that existed from 1932 to 1961.
 It was the provincial wing of the national CCF.
 The party had no leader in the beginning, and was governed by a provincial council and executive.
 The party first Member of the Legislative Assembly (MLA) was elected by voters in the 1934 Ontario general election.
 In the 1937 general election, no CCF members were elected to the Ontario Legislature.
 In 1942, the party elected Toronto lawyer Ted Jolliffe as its first leader.
 He led the party to within a few seats of forming the government in the 1943 general election; instead, it formed the Official Opposition.
 In that election, the first two women were elected as CCFers to the Ontario Legislature, Agnes Macphail and Rae Luckock.
 The 1945 election was a setback, as the party lost most of its seats in the Legislature, including Jolliffe's seat.
 The party again became the Official Opposition after the 1948 general election, and defeated the Conservative premier George Drew in hisseat, when Bill Temple unexpectedly won in the High Park constituency.
 The middle and late 1940s were the peak years for the Ontario CCF.
 After that time, its electoral performances were dismal, as it was reduced to a rump of two seats in the 1951 election, three seats in the 1955 election, and five seats in the 1959 election.
 Jolliffe stepped down as leader in 1953, and was replaced by Donald C. MacDonald.
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.

Albert Oliver Badman (18 December 1885 – 24 April 1977) was an Australian politician.
 Born in Yacka, South Australia, he was educated at state schools before becoming a wheat farmer and wheat breeder.
 He was a Methodist lay preacher and President of the South Australian Country Party before entering Parliament.
 In 1931, he was elected to the Australian Senate for South Australia, representing the Country Party.
 In 1937, Badman transferred to the House of Representatives, winning the seat of Grey.
 The United Australia Party (UAP) did not contest the seat as the Country Party had agreed to allow the UAP's sitting member for Grey, Philip McBride, to take Badman's place in the Senate.
 Together with fellow Country Party members Arthur Fadden, Bernard Corser and Thomas Collins, Badman dissociated himself from party leader Earle Page after the latter made attacks on the leader of the UAP, Robert Menzies; the exclusion of these four led to the election of Page supporter Archie Cameron as the party's next leader.
 In 1940, Cameron defected to the UAP, and the Country Party in South Australia ceased to exist; Badman became, in effect, a UAP member.
 He was defeated in 1943, and returned to farming.
 He was President of the Primary Producers' Union of South Australia from 1954 to 1961.
 Badman died in 1977.
