The Green Party of England and Wales has an eco-socialist group, Green Left, founded in June 2005. Members of the Green Party holding a number of influential positions, including former Principal Speakers Siân Berry and Derek Wall, as well as prominent Green Party candidate and human rights activist Peter Tatchell have been associated with the grouping. Many Marxist organisations also contain eco-socialists, as evidenced by Löwy's involvement in the reunified Fourth International and Socialist Resistance, a British Marxist newspaper that reports on eco-socialist issues and has published two collections of essays on eco-socialist thought: Ecosocialism or Barbarism?, edited by Jane Kelly and Sheila Malone, and The Global Fight for Climate Justice, edited by Ian Angus with a foreword by Derek Wall.
