The Government has vastly underestimated the cost of building a new generation of nuclear power plants, according to the head of the world's largest power company.
Wulf Bernotat, chairman and chief executive of E.ON, the German energy giant that owns Powergen, has told The Times that the cost per plant could be as high as €6 billion (£4.8 billion) - nearly double the Government's latest £2.8 billion estimate.
