Sept 13 (Reuters) - BlackRock ( BLK ) plans to invest

500 million pounds ($700 million) in British data-centre

infrastructure, one of a string of deals to be announced during

U.S. President Donald Trump's state visit next week, Sky News

reported on Saturday.

BlackRock ( BLK ) and Downing Street did not immediately respond to

Reuters requests for comment on the report, which said BlackRock ( BLK )

would invest through a new venture with Digital Gravity

Partners.

BlackRock ( BLK ) CEO Larry Fink will join OpenAI's Sam Altman and

Blackstone's Stephen Schwarzman as part of the business

delegation accompanying Trump, Sky News reported this week.

Altman and Nvidia ( NVDA ) CEO Jensen Huang plan to pledge

support for billions of dollars in British data-centre

investments during the trip, Bloomberg News reported on

Thursday.

The investments underscore rising demand for digital

infrastructure, driven by artificial intelligence and cloud

computing.
