Salesforce, the US software firm, has revealed a $4bn (£3.2bn) investment in the UK.
The company, which specialises in customer relationship management tools, said strong demand was behind its decision.
The investment will be spread over five years and follows a $2.2bn sum spent since 2018.
“Salesforce is experiencing rapid growth in the UK as companies invest in their digital transformations and leverage the incredible innovation cycle around artificial intelligence (AI)”, its statement said.
It will be seen as a boost to the country’s tech industry just weeks after Microsoft’s president criticised a regulatory decision to block its takeover of Activision Blizzard, saying it had “shaken confidence” in Britain.
The company is appealing the Competition and Markets Authority’s decision.
PM Rishi Sunak said: “Salesforce’s major investment in its UK business over the next five years is a ringing endorsement of our economy.
“It will strengthen the company’s UK presence, increasing capacity, as well as creating vital jobs, reinforcing our position as one of their largest markets outside of the US.”
