Miliband vows climate leadership if he becomes PM

Ed Miliband will promise to provide global leadership on tackling poverty and climate change if he wins the General Election in May.

In a speech later today, the Labour leader will insist that a commitment to the green agenda and a desire to reduce inequality are "at the heart of my beliefs" rather than being "part of a branding exercise".

Miliband will promise to use a series of major global summits after the election to push for action to eliminate extreme poverty by 2030 and reduce global net carbon emissions to zero by 2050.

He is also set to reaffirm Labour's commitment to decarbonising the UK's electricity supply by 2030 and claim that "tackling climate change is the most important thing I can do in politics for my children's generation".
