Lehman Brothers Holdings Inc, the US investment bank that filed the largest bankruptcy in history, won federal court approval to sell its North American business to London-based Barclays Plc for $1.75 billion. US Bankruptcy Judge James Peck in Manhattan overruled objections from Lehman creditors who said the sale was moving too quickly, setting the stage for Barclays, the UK’s third-biggest bank, to close the deal over the weekend. Peck said it was clear no other purchaser would emerge if he delayed the sale, and that the deal would help stabilise global financial markets.
