Lloyds took an extra 450 million-pound PPI charge yesterday for compensation while Barclays earmarked 1.35 billion pounds earlier this week. In all, Britain's banks have set aside more than 15.5 billion pounds for redress. RBS also booked a 385 million-pound charge for legal actions and investigations, without giving further details. The Treasury, which is preparing to cut its stake in Lloyds Banking, has said RBS is still burdened by too many poor assets to be sold. The lender has advanced 1.3 percent this year, staying below the 407-pence price at which the government says it would break even. By contrast, Lloyds, 39 percent owned by the government after a 20 billion-pound rescue, has jumped 54 percent to above the 61-pence break-even price.
