Stephen Michael Alan Haseler was a British academic and advocate for a British Republic. He was a Professor of Government, author of many books on contemporary politics and economics.
Haseler had a long record of political involvement in Britain, having stood for election to the British Parliament for the Labour Party in Saffron Walden at the 1966 general election, when he was the youngest candidate in the country, and in the 1970 general election for the Maldon constituency. He was elected to the Greater London Council for the Wood Green division in 1973, where he was appointed chairman of the General Purposes Committee. In June 1975 he became a founder and joint secretary of the Social Democratic Alliance, a grassroots organisation established on the right of the party to combat "entryism" by extra-parliamentary Marxist and Trotskyist organisations, such as Militant and the International Socialists. Although the new group was supported by the Cabinet minister Reg Prentice, who declared that he would speak in its support on "any platform", the decision to criticise mainstream Labour politicians and trade unionists - including Michael Foot and the railwaymen's leader Sid Weighell - for writing opinion pieces in Communist-backed newspapers did not go down well. Harold Wilson, speaking at the party conference that year, attacked the SDA as an "anti-party group which has been disporting itself in Blackpool this weekend, leaking… their smears to an ever-ready Tory press." Haseler was expelled from the Labour Party in 1980, after the NEC decided by a majority of 23 to 2 that membership of the group was incompatible with party values. He went on to become a founder member of the Social Democratic Party the following year, and in 1982 stood to become the party's president, but took last place with 14.8% of the vote. He later became co-chair of the Radical Society and Chair of the pressure group Republic and honorary chair from 2004-2007. He was on the Pro-Euro Conservative Party list for the London constituency in 1999 European Parliament elections. Although initially an opponent of Britain's membership of the European Economic Community, he later became a staunch European federalist who believed that the only credible future for the UK is in the European Union, and that the only viable future for the peoples of Europe lies in a United States of Europe.
Haseler published extensively, including The Gaitskellites, The Death of British Democracy, The Tragedy of Labour, The Battle for Britain: Thatcher and the New Liberals, The End of the House of Windsor, The English Tribe: Identity, Nation and the New Europe, The Super-Rich: The Unjust World of Global Capital, Super-State – The New Europe and the Challenge to America, Sidekick: British Global Strategy From Churchill To Blair and Meltdown UK. His book, Grand Delusion: Britain in the Age of Elizabeth II, was written to coincide with the Diamond Jubilee of Queen Elizabeth II.
