Balfour Beatty, the infrastructure firm, was the heaviest faller after saying that its UK construction business is expected to deliver "significantly lower profits" from operations in 2013 than its previous expectations. High Street bakery chain Greggs was also declining sharply after saying that profits for the full year would be slightly below the lower end of market forecasts. Adding to its woes, Panmure Gordon cut its estimates for the stock following a profit warning, but maintained its 'buy' rating. UBM was making decent gains after Citigroup raised its target price from 749p to 800p, upgrading the stock to buy.
