Conservative, Labour and Liberal Democrat party leaders sign up to new pledge on tackling climate change
In an unusual move in the prelude to an election, David Cameron, Ed Miliband, and Nick Clegg have signed a joint pledge to continue to support policies to fight climate change.
The leaders of the three big parties in Westminster have agreed to stick to the UK's goal of slashing carbon emissions, to phase out all coal-fired power plants without carbon-capture equipment, and to work on making a global climate deal to be signed this year legally binding.
The novel agreement, brokered over several months by environmental groups, the Women's Institute and Christian Aid, is an attempt to take climate change out of the political arena. It marks a shift for Mr Cameron, who has presided over a Conservative party riven by disagreements over the issue.
