Barclays is overhauling the department tasked with policing the behaviour of its investment bankers following a wave of high-profile exits from the financial giant’s compliance team since chief Jes Staley was fined for attempting to unmask a whistleblower.

Daniel Hodge, the chief compliance officer for Barclays International — who manages a unit of several hundred staff that includes corporate and investment banking — signed off on the changes soon after taking on his new role at the bank in April, according to a person with knowledge of the situation.
