The prime minister and chancellor hope to revive talks with SoftBank, which is said to have halted plans to explore a London listing after political turmoil as Boris Johnson resigned.

The lobbying effort was led by Gerry Grimstone, the former investment minister. However, he left the government after Johnson’s resignation. Chris Philp, the former digital technology minister who was also part of the charm offensive, now works alongside Kwarteng as chief secretary to the Treasury.
