Miliband: UK 'sleepwalking into a national security crisis'

Ed Miliband has attacked the Prime Minister for giving up the fight against climate change, warning that Britain is "sleepwalking into a national security crisis".

The Labour leader said the winter storms that have been wreaking havoc in the country should serve as a "wake up call".

It was "extraordinary" that the Prime Minister was now portraying climate change merely as "a matter of conscience", when it had been a "core conviction" when he was in Opposition.
