Sefton Central Labour MP BIll Esterson told Parliament this week that the government wasn't doing enough to help older people and hardworking families cope with rocketing household energy bills.
Speaking during a debate in Westminster, Bill told Tory-Lib Dem Government Ministers that they were failing to tackle the household energy bill scandal.
During the debate, Bill said: "A disabled pensioner couple summed up the views of many my constituents when they told me they pay over £3,000 a year for electricity and gas combined. And now that bills are set to rise yet again, their bill will go up by another £300. My constituents would benefit from Labour's plan to put all over 75s on the cheapest tariff."
Speaking afterwards, Bill said he feared that the extortionate cost of household gas and electricity would mean that people will die this winter.
Bill said: "People are struggling. Families are struggling. Older people are struggling. Extortionate energy costs are pushing people below the poverty line. And this Tory-Lib Dem Government isn't doing enough to help.
"Lib Dem Energy Minister Ed Davey's best suggestion is for people to switch energy suppliers. Number 10's suggestion is for people to put on an extra jumper.
"They just don't get it. People are fearing to put their heating on this winter because of the rocketing costs. They can't afford to keep warm in their own homes.
"It is going to lead to deaths. That's the stark fact of the matter that cannot be ignored.
"And the best advice that the Lib Dem Energy Minister can give is to swap suppliers. Mr Davey, they are all putting their prices up.
"The best advice David Cameron and his team can give is to put an extra jumper on. Not only is this an insult, but it shows just how out of touch this government is. It shows they are more interested in looking after the interests of the big energy companies at the expense of the rest of us."
Bill said urgent action is needed to save lives this winter.
Bill said: "The ever rising fuel bills cannot be allowed to continue. Pensioners were making the decision last winter whether to eat or heat. This year I fear the decision will be made for them as they won't be able to afford their energy bills anyway.
"This will lead to unnecessary deaths.
"That is why Labour is calling for a freeze on energy bills and for new rules that insist that over 75s must be automatically placed on the cheapest tariff. Common sense measures that would save lives.
"These are steps that need to be taken right now. Simple steps that will save lives this winter. Simple steps that will begin to tackle the household energy bill scandal."
