Nuclear plans 'should be rethought after fall in offshore windfarm costs'

Lib Dems and green groups say reduced price of state support should sound death knell for plants such as Hinkley Point C

The government is under pressure to reconsider its commitment to a new generation of nuclear power stations after the cost of offshore wind power reached a record low.

Experts said green energy had reached a tipping point in the UK after two windfarms secured a state-backed price for their output that was nearly half the level awarded last year to Britain's first new nuclear power site in a generation, Hinkley Point C.
