Peter Gary Tatchell (born 25 January 1952) is an Australian-born British political campaigner best known for his work with LGBT social movements (lesbian, gay, bisexual and transgender).Tatchell was selected as Labour Party Parliamentary candidate for Bermondsey in 1981. He was then denounced by party leader Michael Foot for supporting extra-parliamentary action against the Thatcher government. Labour subsequently allowed him to stand in the Bermondsey by-election in February 1983. In the 1990s he campaigned for LGBT rights through the direct action group OutRage!, which he co-founded. He has worked on various campaigns, such as Stop Murder Music against music lyrics allegedly inciting violence against LGBT people and writes and broadcasts on various human rights and social justice issues. He attempted a citizen's arrest of Zimbabwean President Robert Mugabe in 1999 and again in 2001.In April 2004, he joined the Green Party of England and Wales and in 2007 was selected as prospective parliamentary candidate in the constituency of Oxford East, but in December 2009 announced he was standing down due to brain damage he says was caused by a bus accident as well as damage inflicted by Mugabe's bodyguards when Tatchell tried to arrest him in 2001, and by neo-Nazis in Moscow while campaigning for gay rights.
