Barclays boss Jes Staley unveiled a reshuffle among its most senior executives, promoting a clutch of long-serving bankers as the UK lender looks for closer links between its investment banking, trading and corporate banking units.

C S Venkatakrishnan, the group's chief risk officer, has been named head of global markets, replacing Stephen Dainton, who has held the role since June 2019, according to Staley's memo to staff seen by Financial News.
