Tories set to block Navitus Bay windfarm off Jurassic Coast

Energy minister Lord Bourne expected to bow to lobbying by local Tory MPs and veto plan for 121 turbines 10 miles off Dorset coast

The government is expected to turn down an application for a 3.5bn windfarm off the south coast of England in what would be another major setback to green energy under the Conservatives.

The decision on the Navitus Bay project off Bournemouth will be announced by Lord Bourne, the energy minister, on Friday just as 13 leading investors have written to the chancellor urging a more supportive attitude towards renewables.
