The Telegraph is reporting that the government body charged with reviewing major state projects has sounded the alarm bell over UK energy policy.
Up to six flagship projects have been classified as "high risk" by the spending watchdog, including new nuclear power stations and key reforms of the electricity market.
However, the watchdog is “doubtful” that Britain can have a reliable energy supply from green sources and keep energy bills affordable under the current plans.
The authority, set up by David Cameron last year, has described the Coalition’s plans to encourage more wind farms and nuclear power stations as “feasible”.
