Wind turbines around the UK are sinking into the sea because their foundations are suffering from subsidence, according to Dong Energy, a Danish wind turbine owner, The Sun newspaper reports.

A wind farm off Essex and another in Liverpool Bay have been found to have the flaw and checks are to be made of turbines at Blyth, Northumberland and Robin Rigg in the Solway Firth.

Up to 336 of the UK’s turbines are at risk and will take £50 million to fix.
