Guardian: A Conservative cabinet minister has claimed drilling for shale gas could make the "single biggest difference to the cost of living" for people in Britain.
Chris Grayling, the justice secretary, said he believes the controversial process known as fracking is the "solution" to the problem of high energy bills.
He spoke out on the first day of the Conservative conference as the party comes under pressure to respond to Labour leader Ed Miliband's promise to freeze energy bills.
