Rainbow Labour is part of the New Zealand Labour Party.
 It started as a branch in Chris Carter's Auckland Waipareira electorate in 1997, just after Chris Carter had been narrowly defeated in the election the previous year.
 At about the same time, Tim Barnett, newly elected to Parliament as an openly gay man, started a Rainbow branch in Christchurch.
 During the next few years the branches expanded in size, with the Auckland branch becoming one of the largest in the Labour Party.
 This led to the formation of a Rainbow Sector Council within the Labour Party, which gave the branches a nationwide focus and co-ordinating body.
 In 2004, at a vote at the Party's Annual Conference, Rainbow Labour was invited to nominate candidates for a permanent representative position elected from the floor of Conference, on the Party's controlling body, the New Zealand Council.

 He served as a Member of the House of Representatives from 3 June 1986 until 22 August 1994 when he became Minister of Social Affairs and Employment in the Cabinet Kok I following the Dutch general election of 1994.
 At the end of the parliamentary period, he was not included in the Cabinet Kok II after the Dutch general election of 1998 by his own request, as he wanted to focus his energies on his candidacy to succeed Wim Kok as the next Party leader of the Labour Party.
 Melkert returned to the Member of the House of Representatives on 13 July 1998 and became the Parliamentary leader of the Labour Party in the House of Representatives on 13 July 1998 and became the presumed de facto next Party leader of the Labour Party in all but name.
 He was elected the official Party leader of the Labour Party on 15 December 2001 and became the lijsttrekker (top candidate) for the Dutch general election of 2002.

 He served as Member of Parliament for South Gloucestershire and later for Great Grimsby.
 Throughout his long career he occupied the cabinet positions of Secretary of State for Education and Science, President of the Board of Trade, Secretary of State for Local Government and Regional Planning and Foreign Secretary.
 A prominent socialist intellectual, he became one of the Labour Party's revisionists on the right, as an intellectual leader of Gaitskellism.
 His highly influential book "The Future of Socialism" (1956) argued against many Marxist notions and Labour Party orthodoxy that public ownership was essential to make socialism work.
 He offered positive alternatives to both right and left wings of his Labour Party.
 He questioned the need for public ownership of the means of production – the classic socialist formulation – and argued instead for making the highest priority the end of poverty and improved public services.
 He led the Labour battle to replace grammar schools with comprehensive schools that did not sort students at age 11.
 As foreign secretary he promoted détente with the Soviet Union.
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.
