Former Prime Minister Sir John Major has told the BBC that energy price rises are unjustified.
He said the government should impose a "one-off windfall tax" on energy firms if Whitehall was forced to pay out a lot of money this winter to help people who were being forced to choose between "keeping warm and eating".
A Downing Street spokesman said: "We have no plans for a windfall tax. It's an interesting contribution to the debate but we are focussed on getting people on to the lowest tariff and on the long term competitiveness of the market".
