The directly-elected mayor of Bristol has said Wales' economy would be damaged by a barrage across the Severn Estuary.
George Ferguson said the barrage would have a detrimental impact if trade at the port of Avonmouth is affected as a result of the proposed £30bn project.
Campaigners for the barrage claim it could provide 5% of the UK's electricity and create thousands of jobs.
Mr Ferguson spoke to Sunday Politics Wales presenter Carl Roberts.
