Robert Wiseman Dairies has signalled a rise in prices for its liquid milk farmers in the autumn in a bid to ensure supply in the face of increased competition from cheese producers.

Cheese manufacturers had continued to increase the amount paid for raw milk in recent months, the company said as it published its interim management statement this week.

To ensure security of supply through the winter, Wiseman which only supplies liquid milk anticipated its farmgate milk price would rise in the ­autumn.
