Scottish wholesaler Inverarity Morton has hired former Wallaces Express boss Brian Calder to conduct a full audit of the business with a view to improving its offering.

Calder started working at Wallaces in 1975 and took over as managing director in 2000, when he set about overhauling the business.

He sold off its pubs and shops to focus solely on wholesaling, before staging a management buyout in 2003 and then selling it to C&C in 2004.

Calder has also served as chief executive at Tennent Caledonian Breweries and Inverarity Morton hopes his “incisive business acumen” and wholesale knowledge will help transform the business, which supplies more than 3,000 on-trade outlets in Scotland.

Stephen Russell, managing director at Inverarity Morton, said: “Brian is an incredibly astute businessman and knows the trade, knows the marketplace inside out.

“He made a very bold, but canny, decision to completely reshape Wallaces Express and then steered it over a relatively short time to become the most successful wholesaler in Scotland. At the time of the C&C acquisition, Wallaces had a turnover of £90 million and employed over 300 people.

“We have asked him to come in and conduct a full audit of the business, looking into every nook and cranny from the product range to systems and policies.”

Calder will serve as non-executive director for the firm.
