Sir Keir said: “The world is more dangerous than it has been for a generation, with conflict abroad washing up on our shores.
“That’s why I’m focused on making the UK the best place to do business by offering global investors the stability and competitive environment they need to grow, even in the face of global uncertainty.
“These investments will create thousands of high-skilled jobs, back British innovation and strengthen our energy system so families are better protected from global shocks.”
The Prime Minister is working with G7 partners to ease pressures on global energy markets, including efforts to stabilise key shipping routes and de-escalate tensions in the Middle East to help bring down costs for households.
