Remember when the Prime Minister surprised everyone a couple of weeks ago by saying he would compel energy companies to put customers automatically on to the lowest tariff?
His ministers found it a bit tricky to explain how exactly that could work, in fact the energy department didn't even know he was going to make that announcement!
Well, I've just been told that tomorrow the Government is going ahead and publishing its plans.
They are unlikely to deliver exactly what the Prime Minister promised, but the Government will claim the proposals could cut bills for millions of households.
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.
