In some parliamentary systems, politicians are said to cross the floor if they formally change their political affiliation to a political party different from the one they were initially elected under. In Australia though, this term simply refers to Members of Parliament (MPs) who dissent from the party line and vote against the express instructions of the party whip while retaining membership in their political party.
In the Australian Senate, Senators vote in favor of a motion by sitting on the benches to the president's right (left of photo), and against it by sitting on the benches to the president's left (right of photo)
Sir Winston Leonard Spencer Churchill was a British statesman, soldier, and writer who twice served as Prime Minister of the United Kingdom, from 1940 to 1945 during the Second World War, and again from 1951 to 1955. Apart from two years between 1922 and 1924, he was a Member of Parliament (MP) from 1900 to 1964 and represented a total of five constituencies. Ideologically an adherent to economic liberalism and imperialism, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.
