The government needs to work "harder and faster" to bring down energy bills, the prime minister has said ahead of a summit on gas and electricity prices.

The energy secretary has invited the six biggest power firms to meet consumer groups and regulator Ofgem.

Writing ahead of the meeting, Mr Cameron said they wanted to work out how to create a "trusted, simple and transparent" market.

British Gas and Npower will pledge not to raise prices again this year.
