PROPOSED plans to build an £850 million tidal lagoon in Swansea Bay is splitting opinion among the city's politicians.
The six-mile, U-shaped seawall will go from Swansea docks to near Swansea University's new Fabian Way campus.
The Planning Inspectorate has asked the public to make its representation about the lagoon, which could provide power for 120,000 homes for 120 years.
Swansea West MP Geraint Davies said the project would harm tourism and the views of Swansea Bay.
He said: "It would be a catastrophic mistake setting aside legitimate concerns over contamination of Swansea Bay and the depopulation of the Gower of its sands."
Meanwhile, Sian James has given her backing to the lagoon project. Mrs James, who represents Swansea East, said people had told her the scheme ticked all the right boxes.
She said: "The feedback I get from constituents — and these are the people who matter — is that the lagoon will be good for Swansea. Many who have attended the briefings say they were impressed with the attention paid to environmental issues."
