Sunak woos business elite with royal welcome – but they seek certainty

Bosses have doubts despite glitzy summit seeking investment from US, Saudi Arabia and others

• Nils Pratley: Summit is nice - but 29.5bn figure is pure hype
• UK will not return to Cameron era's close ties with China'

Hampton Court is an enduring monument to the power of Henry VIII, a pleasure palace down the Thames from Westminster and the City of London. On Monday it was the scene of power projection of a different kind, as Rishi Sunak pitched for investment from some of the world's business elite.

Bosses ranging from the US bankers Jamie Dimon of JP Morgan and David Solomon of Goldman Sachs mixed with the leaders of massive investment funds from Abu Dhabi and Saudi Arabia. British bosses also braved the chilly halls - heating was not a strong point of Tudor architecture - ranging from the insurer Aviva's chief executive Amanda Blanc and the Octopus Energy boss Greg Jackson to Lawrence Stroll, the executive chair of Aston Martin.
