David Cameron: Labour's energy price freeze plan 'a con'

Prime Minister David Cameron has criticised Labour's plan to freeze energy prices, but maintains he wants to see low energy bills for 20 years to come.

Speaking at a PM Direct event in York, he said it was important to work on using new sources of fuel.

"I want to see energy bills low not just for 20 months, I want to see them low for 20 years," he said.
