The story
The Co-operative Retail Trading Group (CRTG) was established in 1993 by the Co-operative Wholesale Society to centralise buying power for retail co-operatives in the UK. By 2002 it had become the central buying group for all of the major food retailing co-operatives, after being joined by the last two independent societies. The CRTG lost its complete control over the food co-op sector in 2014 however after the Clydebank Co-operative Society left the buying group. After the financial crisis in The Co-operative Group it was decided that The Group should no longer be responsible for the central buying group (the CRTG) as, if it had have collapsed, it could have led to the collapse of the independent co-operative societies as they would have had major difficulties in sourcing produce.
