Friday The London Stock Exchange will reveal quite how much it has been helped by the turmoil in the Italian banking system on Friday when it releases its preliminary results, with Numis' James Hamilton believing the bourse's net treasury income will have more than doubled. Also updating the market on Friday is All Bar One and Harvester owner Mitchells & Butlers, whose interim results follow in the wake of figures this week from rivals Enterprise Inns and Marston's. The pubs company - which still hasn't found a replacement for former chief executive Adam Fowle, who left over a year ago -is expected by Peel Hunt's Paul Hickman to have seen a slowdown in like-for-like sales growth over the second-quarter, resulting in a rise of 3% for the first six months of the year.
