The Energy Secretary Ed Davey, when pressed on repeating the Prime Ministers comments on Wednesday that, "energy companies will have to offer customers their lowest tariff"
He said: "He welcomed Ofgems proposals to help consumers get the best available tariff." And added: "He will take Ofgems proposals forward."
It is possible that some of the best deals on the market will disappear. We could lurch from a minefield of deals to virtually none at all.
Downing Street sources are adamant tomorrow's energy bills announcement will stick to David Cameron's promise of lower tariffs, but will it?
Ministers are poised to announce plans to decrease energy bills in a bid to get customers on the lowest tariffs available.
