Gordon Brown has called for the temporary re-nationalisation of energy companies if they fail to cut the cost of gas and electricity over the winter.
The former Labour Prime Minister said the energy price cap that will see household energy bills rocket to £4.200 in January should be cancelled and for the government to negotiate new lower prices with the companies.
If they refuse to co-operate Brown said emergency action should be taken and that energy suppliers should be temporarily nationalised to protect consumers, just as he did with some of the banks in 2009 during the financial crisis.
