The deal which could pave the way for a new nuclear power station in Sizewell has been given the thumbs down by the Liberal Democrats.

Grassroots, who vote for party policy at their conference each year, agreed the deal to build Hinkley Point - which was given the green light by Theresa May last week - was poor value for money.

This was despite a plea not to rule it out from the senior Liberal Democrat and former energy minister Ed Davey who negotiated the original deal

He told activists they should not be dismissing any sources of low-carbon energy, adding: 'We should not be taking nuclear off the table because of the risks posed to our children and their children by climate change.'

But the party voted in Brighton to oppose the construction of the new plant, agreeing that represents very poor value for money for UK consumers.

The said UK energy strategy should rest on energy efficiency, renewable energy, storage and interconnection with European grids.

Lynne Featherstone, Liberal Democrat Energy Spokesperson, said: 'Failing to call a stop to Hinkley will prove a costly mistake. Not just the financial cost to consumers and the public purse, but the opportunity cost for renewables.

'The opportunity to pull the plug on Hinkley has been missed, and we will all pay for it from our pockets.'
