(Sharecast News) - Tesco said on Thursday that UK chief executive Jason Tarry will step down next March after more than 33 years at the company, to be succeeded by former Aldi executive Matthew Barnes.

Tarry has been CEO of the UK business for the past six years.

Group CEO Ken Murphy said: "Jason has made an immense contribution to our business. Under his leadership, Tesco today is the most competitive we have ever been, built on exceptionally strong foundations of doing the right thing for our customers and colleagues.

"His values and commitment to creating a high performing, supportive and diverse culture have been key to creating the Tesco we know today."

Tesco said Barnes is a "highly accomplished" retailer, having worked in many senior positions in Aldi.

He was previously UK & Ireland CEO before being promoted to co-head of Aldi Sud's Executive Board, where he had responsibility for many of Aldi's international businesses and its global sourcing, buying & supply chain.
