Building new nuclear power plants could boost the British economy, business secretary and former nuclear sceptic Vince Cable said on Monday. Speaking at a nuclear suppliers' event organised by EDF Energy, the French company planning to build Britain's first nuclear plants in decades, Cable said he used to have much "scepticism towards nuclear economics". But Cable, a former university economics lecturer and chief economist at oil and gas giant Royal Dutch Shell said that a 40 billion-pound investment in new reactors could help the British economy. Cable's Liberal Democrat party has in the past largely opposed nuclear energy but agreed not to oppose plans for new plants as part of coalition deal with the pro-nuclear Conservative party formed in May 2010. "These projects can help revitalise entire sectors of the British economy and create a UK industry with the skills to export and compete around the world," said Energy Minister
