DAVID CAMERON, Nick Clegg and Ed Miliband have jointly pledged to work “across party lines” to agree cuts to Britain’s carbon emissions.

The agreement, signed by the three party leaders yesterday, was brokered by think tank Green Alliance, backed by Christian Aid, Cafod, Greenpeace, RSPB and WWF.

They also signed up to seeking a “fair, strong, legally binding” international climate deal, due to be negotiated in Paris at the end of the year, to limit global temperature rises to below 2°C.
