Arriving ahead of an EU meeting in Brussels David Cameron has said the government will use the new energy bill to make energy suppliers give customers the lowest tariff, saying, "we will ensure that customers get the lowest tariffs."
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.
