The body representing energy companies has given its reaction to the prime minister's suggestion that MPs needed to "roll back some of the green regulations and charges that are putting up bills".

Chief executive of Energy UK Angela Knight told BBC Breakfast: "There are some costs which - if they are relieved off the bill - will make a very decent and good difference to households".
