A weak morning session on Wall Street did London no favours Thursday, although the big banks helped the leading index to only its second close above 5,800 in over three weeks.Barclays, Lloyds and Royal Bank of Scotland were top of the pile. HSBC also did well, but fellow Asia-focused player Standard Chartered missed out.It propped up the leading index after warning that cost growth will exceed income growth as the bank invests in its businesses, opens new branches and hires new staff.
