The FTSE 100 fell into the red on Wednesday, weighed down by a stronger pound and a drop in Standard Chartered shares as investors lamented the bank's decision to withhold a shareholder dividend.
London's blue chip index closed lower by 0.16% or 12.23 points at 7,411.43, with Standard Chartered shares dropping 6% or 51.2p to 795p.
It comes despite a 93% leap in half-year profits, thanks to restructuring efforts, with investors lamenting news the bank would not resume dividend payouts amid "regulatory uncertainties."
The group said it would review its dividend policy at the end of the year.
David Madden, a market analyst at CMC Markets UK, said: "A lack of a dividend pushed shares in Standard Chartered lower today despite a good set of numbers.
"The bank saw rising revenue and profits, and the loan impairment charges slumped but it still wasn't enough to coax buyers.
"Seeing as the business is bouncing back, investors now feel it is time to reinstate the dividend."
The FTSE was also hit by sterling strength against a weak US dollar, with the pound rising nearly 0.2% to 1.323 versus the greenback.
Against the euro, the pound was down 0.2% at 1.115.
Investors were also digesting data showing that the UK construction industry endured a shock slowdown last month, sliding to its lowest level for nearly a year as commercial building eased.
The closely watched Markit/CIPS UK Construction purchasing managers' index (PMI) fell to 51.9 in July, down from 54.8 in June with economists expecting a figure of 54.1. A reading above 50 indicates growth.
Across Europe, the French Cac and German Dax ended the day down 0.39% and 0.57%, respectively.
Brent crude prices were up 1.3% at around 52.13 US dollars per barrel, after US data showing a further drop in crude inventories stateside.

BAE Systems dropped 16.5p to 590.5p after the defence giant warned that it would take a charge in the second half for overhauling its cyber and intelligence arm, where revenues are "softening".
William Hill surged 15.4p to 268p despite reporting an 11% fall in pre-tax profits to £109 million in the six months to June 28, while revenue grew 3% to £837 million.
