Barclays corporate and investment banking revenues fell in the second quarter – despite fixed income and advisory performing well – but chief executive Jes Staley said the UK bank's strategy had not been changed by the June 23 referendum result.

In CIB, which Staley has overseen since the March departure of divisional head Tom King, revenues for the three months to June 30 fell to £2.6 billion from £3.3 billion a year earlier, according to a results presentation published on July 29, while pre-tax profits fell 44% to £909 million.
