New Barclays boss Antony Jenkins insisted the bank is in good shape despite a torrent of scandals and a £47m quarterly loss.
Delivering his first set of results since taking over from Bob Diamond in the wake of the Libor-fixing affair, he said the lender had "much to do to restore trust among stakeholders".
Barclays reported a statutory loss of £47m in the three months to September, compared with a £2.4bn profit in the same quarter last year. The loss was driven by a £700m hit to cover mis-sold PPI claims and a one-off £1bn charge against the value of the bank's own credit.
The bank reported underlying pre-tax profits for the third quarter of £1.7bn, compared with £1.3bn last year. Shares in Barclays fell nearly 4%.
