Jeremy Hunt must act now to reverse plans to raise energy bills from April, MoneySavingExpert’s Martin Lewis has warned, saying the change cannot wait until the spring budget next month.

In a letter to the chancellor seen by the Guardian, Lewis warned more than 1.7m more households could be plunged into fuel poverty if he does not urgently commit to freezing energy prices.
