London midday: Footsie hobbled by resource stocks

Resource stocks are dragging London lower despite a good showing by retailers. Lower commodity prices are largely responsible for the sell off of commodity stocks, though legal battles also hover over a couple of stocks. BP is lower in line with weaker oil prices, with the oil giant suffering more than its peers as investors mull over the prospect of the US authorities bringing a court case against the company for its part in the Gulf of Mexico oil spill catastrophe.
