Turner returns to the UK from the Czech Republic where he has held the role of country manager for Tesco’s operations in the Czech and Slovak republics for the past five years.
The retailer launched into the region in 1996 and currently operates 28 stores and hypermarkets, employing 13,000 people and serving between 1.5 million and two million customers a week.
Last year profits for the region increased by more than 20% in the year to end February 26.
Turner will take up his new role in September, heading One Stop’s 500 stores. He replaces Steve Murrells who left the role earlier this year to become Tesco’s commercial director for fresh food with responsibility for produce, meat, fish and poultry.
He has been at Tesco since 1992, having joined from Sainsbury’s where he headed a buying department.
One Stop’s trading director, Bill O’Neill, had been acting in the CEO role in the interim.
Tesco acquired the One Stop chain after it bought T&S Stores in 2002 for £377m. In June the retailer pledged its long-term support to the fascia by converting newly acquired stores to the fascia despite having converted 347 of the original 800-store One Stop chain to its Express format.
