Jerry Marwood is to be succeeded as Spar managing director by Debbie Robinson, former director of food marketing at the Co-operative Group.

In her role at the Co-op Group, Robinson developed award-winning layout, merchandising and design for c-stores and forecourts, and initiated a 3,000-plus own-brand range.

She also developed the Co-op's 'Good with food' campaign, and helped to develop its ethical retailing approach.

Spar chairman Peter Blakemore said of her appointment: "Debbie brings with her a wealth of retail experience and her passion and knowledge will be invaluable to our business."
