John Martin McDonnell is a British Labour Party politician, who has been the Member of Parliament for Hayes and Harlington since 1997; he serves as Chair of the Socialist Campaign Group, the Labour Representation Committee, and the "Public Services Not Private Profit Group". He is also Parliamentary Convenor of the Trade Union Co-ordinating Group of eight left-wing trade unions representing over half a million workers. McDonnell attempted to stand for the post of Labour Party leader following Tony Blair's resignation in 2007 but was unable to gain sufficient nominations. He was a candidate for Leader again in 2010 following Gordon Brown's resignation but withdrew in favour of Diane Abbott, feeling that he would be unable to secure enough nominations.
