By Matt Chorley, Mailonline Political Editor PUBLISHED: 09:33 EST, 17 October 2012 | UPDATED: 13:01 EST, 18 October 2012 David Cameron was tonight scrambling to rescue his plan to force energy companies to give all their customers their cheapest deals, amid growing doubt about how it will work in practice. The Prime Minister arrived for talks with European leaders in Brussels trying to clarify his announcement, after Downing Street earlier refused to confirm it would be included in the forthcoming Energy Bill. Mr Cameron insisted he wanted to be 'on the side of hard pressed, hard working families who often struggle to pay energy bills' after opponents accused him of making up policy 'on the hoof'.
