Carpetright announced the departure of Chief Executive Darren Shapland as it warned falling sales meant full year profits would be 'significantly' below its previous expectations. The carpet retailer said founder and Chairman Lord Harris of Peckham would take control and become full-time Chairman. Carpetright's Trading Director Graham Harris, who is no relation to Lord Harris, will join the board and become Chief Operating Officer. WS Atkins shares also took a hit after the group's 'hold' rating was reiterated by Jefferies Group. Wood Group also declined after revealing that uncertainty over its oil sands remains, and despite telling investors it is confident of achieving growth in the full year in line with expectations.FTSE 250 - RisersOcado Group (OCDO) 419.70p +4.14%Bank of Georgia Holdings (BGEO) 2,000.00p +3.79%Greggs (GRG) 428.90p +3.08%Kenmare Resources (KMR) 29.00p +2.51%Centamin (DI) (CEY) 45.47p +2.46%WH Smith (SMWH) 854.00p +2.34%Dixons Retail (DXNS) 46.66p +2.21%888 Holdings (888) 168.10p +2.19%Regus (RGU) 195.30p +2.14%Kier Group (KIE) 1,708.00p +2.09%FTSE 250 - FallersCarpetright (CPR) 626.50p -6.98%Alent (ALNT) 330.10p -3.22%Soco International (SIA) 406.40p -2.54%IP Group (IPO) 136.10p -2.30%PZ Cussons (PZC) 401.00p -2.24%Balfour Beatty (BBY) 275.40p -2.20%PayPoint (PAY) 1,055.00p -2.04%Aveva Group (AVV) 2,561.00p -1.88%Micro Focus International (MCRO) 760.00p -1.87%Mitchells & Butlers (MAB) 392.90p -1.80%NR
