Labour's Shadow Energy and Climate Change Secretary, Caroline Flint, says customers will not understand how energy companies can get away with inflation-busting price rises when their profits are already increasing. She said:
"In the wake of the allegations this week about price fixing in the electricity and gas markets, the time has come for a complete overhaul of our energy market.
"We need a One Nation government to break the dominance of the energy giants, open up the energy market, protect vulnerable customers from being ripped off and create a tough new energy regulator with the power to force energy companies to pass on savings to consumers."
