Scotland's largest independent dairy Graham's has bought Lothian based dairy Country Fresh in a deal that will increase its capacity by another 500,000 litres of milk a year. Graham's accountant Jackie Farrell said the acquisition was just the latest in a series of purchases made by the Sterling based company as it continues its "aggressive expansion campaign". A key supplier of milk and dairy products to Scotland's independents, Graham's has been steadily acquiring smaller Scottish dairy businesses in the past few years. "Since I joined the company three years ago, our turnover has trebled to over £12m," said Farrell. {{NEWS }}
