Tidal lagoon: Could Swansea Bay become world first?

Plans for a £1.3bn tidal lagoon in Swansea Bay have been backed by a government-commissioned review.

Charles Hendry's independent report into the technology's viability said it would make a "strong contribution" to the UK's energy supply.

He said it was cost effective and would bring "significant economic opportunity".

The UK government still needs to agree on a deal and a marine licence would also need to be approved.
