A Japanese corporation is to invest about £4 billion in wind farm projects off the coast of Suffolk and Norfolk.

Sumitomo Electric Industries is also to invest £200 million in an undersea cable factory in the Highlands, the Scottish Government has announced.

Energy Secretary Neil Gray said the Sumitomo Electric Industries plant will create 150 jobs.

The deal was announced last month when Mr Gray visited Japan on a three-day trip and further details were confirmed on Thursday.

The factory will make cables for use by offshore wind farms.

The Highlands project is part of a £17.7 billion package of Japanese investment in the UK being outlined during Rishi Sunak's visit to the country, which includes the £4 billion in wind farm projects off the East Anglian coast.

The Prime Minister said: "These new investments are a massive vote of confidence in the UK's dynamic economy, from some of Japan's top firms.

"Working with the Government and British industry, they will create the kind of high-quality, reliable jobs and transformative local investment we are delivering around the country.

"It's great to also see leading UK businesses seizing the huge opportunities for growth and collaboration in Japan."

The UK Government said very few companies have the ability to manufacture undersea high-voltage cables and the investment will be "vital" to energy security.
