A former Conservative chancellor and ex-energy secretary has criticised the new power plant at Hinkley Point as poor value for Britain.
Lord Lawson of Blaby said he was not anti-nuclear but every independent energy expert had said this was a "thoroughly lousy deal".
He said that French energy company EDF, which has been contracted to build the plant, is "hopelessly behind schedule and in deep, deep trouble" over two similar power stations it is constructing in France and Finland.
The politician called for an assurance that if there are similar problems at Hinkley C the government would have "no hesitation in ending this contract whatever penalties there may be because it is a lousy contract and the sooner it is ended the better".
Why does the government want a new nuclear plant at Hinkley Point and why has it proved so controversial?
Government officialscan't provide any detail about how a national security test for future critical infrastructure deals will be applied.
The government approved new nuclear power plants back in 2006 but the plan for Hinkley was only given the go ahead 10 years later.
