Initial optimism dampened as Barclays chairman warns of 'challenges'
London's top-flight index swung into the red as investors took a dim view of Barclays despite the banking giant posting a significant surge in profits.
The FTSE 100 Index was down 30.88 points to 7,271.37, as the lender saw group pre-tax profits soar to £3.2 billion, up from £1.1 billion a year earlier, thanks to a boost from its investment banking arm.
However, Barclays reversed early gains as shareholders baulked at warnings from chairman John McFarlane that "significant challenges remain" as the bank fights US authorities over allegations surrounding its part in a mortgage bond mis-selling scandal.
Shares closed down more than 2%, or 6.1p to 229.1p.
Jasper Lawler, senior market analyst at London Capital Group, said: " A near tripling of profits in 2016 and the early closure of its so-called 'bad bank' which housed its worst assets were the main reasons for the initially positive reception to Barclays results.
"The profit surge was thanks in part to lower PPI payout costs but with uncertainty over the fine it will pay the US Department of Justice, past discretions continue to be a future liability."

In UK stocks, British Gas owner Centrica slumped after revenues for 2016 dropped 3% to £27.1 billion.
However, annual group operating profits at Centrica jumped 4% to £1.5 billion, helped in part by a 2% rise in operating profits at its energy and services arm covering the UK and Ireland to £906 million.
Shares were down 8.6p to 225.1p.
Away from the top tier, National Express rose 8.2p to 350p after notching up a 10% rise in profits last year thanks to ongoing strike action blighting rival Southern Rail.
Full-year profits rose to £120 million from £109.1 million a year earlier, with the firm's coach arm carrying an additional 25,000 customers on affected Southern routes during recent strike action.
