Downing Street has urged the Financial Services Authority (FSA) and Ofgem to speedily investigate a whistleblower's claim that Britain's wholesale gas market has been frequently manipulated by energy companies. The allegations, revealed by The Guardian, suggest the £300bn market has been fixed in a way similar to bank fiddling of the Libor interest rate. Surprise, surprise, it's just one thing after another. This is what comes from the aggressive privatisation of the utility companies by the Tories, nice on Thatcher and Co. Protect the whistle blower.
