Sunak is in Japan for a Group of Seven leaders' summit and will meet business leaders as Britain prepares to join a trans-Pacific trade pact which includes Japan and Australia.

In a statement, Sunak's government said companies attending the summit such as Marubeni Corporation and Sumitomo Electric Industries had pledged to invest in Britain.

It said Marubeni, a Japanese trading house, had announced its intention to sign an agreement with the government which envisaged approximately 10 billion pounds of investment in Britain with partners over the next 10 years.

Other firms planned to invest in property, the statement said.
