EDF Energy has reached an agreement with China General Nuclear Power Corporation (CGN) to build a nuclear power plant at Hinkley Point, Somerset.

China's leader Xi Jinping is expected to put the seal later on its contribution to what will be the first UK nuclear power plant to be built in a generation.

Chancellor George Osborne has announced that the UK will guarantee a £2bn deal under which China will invest in the Hinkley Point nuclear power station.
