Full report: Former Minister urges Government to get behind Severn Barrage project

A former Minister has urged the Government to get behind the Severn Barrage project.

It would cost a staggering twenty five billion pounds - of private sector money - and according to former Welsh Secretary Peter Hain, would generate five per cent of the country's entire electricity from tidal power.

However it's strongly opposed by conservation groups - who say it would damage internationally-protected mudflats - and by the port of Bristol. Today MPs heard both sides of the argument, as our political correspondent Bob Constantine reports.
