The consumer watchdog said on Wednesday it had provisionally found six Scottish dairies engaged in price fixing between 2000 and 2003.

The dairies were Ballantyne, Grahams, Quothquan, Renfrew, Scottish Milk Dairies and Wiseman, the Office of Fair Trading said, adding that it was too early to say if they had broken competition laws.

The main provisional finding is that the dairies engaged in price fixing by sharing pricing information and co-ordinating a series of price increases between them and colluded over arrangements not to compete for each others' customers, a form of market sharing, it added.
