Work to install the first wind turbines for the world’s largest offshore windfarm off the coast of north-east England has begun as the government tries to shore up confidence in Britain’s green economy.

The energy company SSE expects to install the first of the turbines, which stand at almost twice the height of the London Eye, about 80 miles off the coast by the weekend.
