The owner of the Blacks and Millets stores has expanded its interests in the outdoor market by snapping up a controlling share of Edinburgh-based group Graham Tiso.

The Tiso family will retain a ‘significant shareholding’ but JD Sports Fashion’s Peter Cowgill will take over the role of chairman from Chris Tiso, who will become chief executive.

Heavily indebted Tiso, which also owns the Keswick outdoor retailer George Fisher and Alpine Bikes, said JD Sports’ investment will see bank debt significantly reduced and will provide capital for the company, which posted a loss of more than £1m in 2011.

It attributed in part the drop in revenue to the oversupply of products in the market following the collapse of the Blacks Leisure chain which, ironically, JD Sports snapped up after it entered administration.

The Tiso group was started by Graham Tiso with his wife Maude in 1962, operating from a back room in a boat shop.

The couple’s son Chris took over the running of the business after his father died in a boating accident in 1992. Graham Tiso was a seasoned climber and member of the Scottish Mountaineering Club.

The Tiso brand is expected to remain, with its headquarters remaining in Edinburgh, while coming under the outdoor branch of JD Sports Fashion.
