When Ed Miliband took to the stage in Brighton, doing the energy industry a favour was the last thing on his mind. Yet in the ultimate exercise in irony, it may well transpire that the Labour leader’s rabble-rousing speech did just that. It certainly seemed to serve his purpose, with Labour well up in the polls at the weekend. However, for every consumer and media outlet that has cheered Miliband’s lurch to the left on energy policy, there has been one that has seen the massive holes. Chancellor George Osborne’s decision to dismiss it as a “back of a fag packet” gimmick shows the Conservatives aren’t running scared. Indeed, many inside the market and out are saying that such an ill-thought-through policy could never see the light of the day.
