Former environment minister Michael Meacher today launched his bid to succeed Tony Blair as leader of the Labour Party under a banner promising "peace, social justice, climate survival".
Mr Meacher insisted it was not a "foregone conclusion" that Gordon Brown would be the next leader, and said he was "fully confident" of receiving the 44 MPs’ nominations needed to get on to the ballot paper alongside the Chancellor.
Launching his bid at Westminster, he unveiled a policy platform including complete withdrawal from Iraq and no involvement in any military action against Iran, opposition to Trident and nuclear power, a #7-an-hour minimum wage and measures to reduce the difference in pay between the richest and poorest.
And he said that "profound change" would be needed in every aspect of the British way of life to meet the threat of climate change.
The Oldham West and Royton MP was flanked by Ian Gibson and Kelvin Hopkins, two prominent backbenchers from the Labour left, as he launched what he said was a "centre-left" bid for the leadership.
But he insisted his candidacy would not split the left, as he believed that John McDonnell - chairman of the Socialist Campaign Group of MPs and the only other declared candidate to succeed Mr Blair - could not secure the necessary support to get on to the ballot paper.
