Sir Michael Fallon is calling on the Department for Business, Energy and Industrial Strategy to set a target of all offshore wind turbines containing at least 60pc British content, a rise of 10 percentage points on current levels.

The former energy minister believes that the growing importance of green energy should be reflected in the UK’s industrial strategy.

Writing to Greg Clark, the Business Secretary, Mr Fallon said the UK is facing a “pivotal moment for offshore wind” – adding that strengthening domestic manufacturers could make Britain a leading player in a fast-growing global industry.

The current target of 50pc UK content is close to being met by some wind farm developers, and Sir Michael now wants the target to be hiked to ensure that more of the £550m earmarked to be spent on turbines by 2025 goes to British companies.
