Profit margins are improving and turnover has topped £10bn, but the co-op movement has got to improve its commercial performance further if it is to realise its social goals, delegates at this year's Co-op Congress at Belfast's Waterfront Hall were told. Co-op union chairman Bob Burlton said: "Societies must resolve to improve further. This will allow co-operatives to continue delivering commercial and social value." Trading profit rose 21.1% to £276m on turnover up 4.7% to £10.2bn. However, return on capital employed (ROCE), which nudged up to 7.8%, was still some way short of the movement's 10% target. {{NEWS }}
