Nisa chief operations officer Amanda Jones and chief executive Neil Turton have announced their departure from the organisation.

Jones has been appointed chief operations officer at Conviviality Retail and will take over the role on 1 December. 

Turton, who has been with Nisa for 23 years, is to move to a senior position in a non-competing business. He will remain in his current role until spring of next year to help recruit a successor.

Nisa chairman Christopher Baker said: “It is testament to the success of Nisa in serving the needs of thousands of members and millions of customers that our top talent is the target of other companies. Neil Turton is one of the longest serving chief executives in grocery retail. He has led Nisa through some seismic changes and the board is hugely grateful for his hard work over 23 years in the business.”

Baker added that the search for Turton’s replacement will begin immediately. “The board has put in place a robust transition strategy and will immediately commence the search for an experienced retailer that will be able to take Nisa to the next stage in its development,” he said. “Neil will manage the succession strategy and continue to drive our retail focus and consumer centric propositions with the existing management team.”

Chief executive Neil Turton said: “After 23 years with Nisa, I’m leaving a business that has just enjoyed an excellent trading year with record volumes and highest ever sales. The company, now more than ever, is retail focussed and consumer centric. I felt it was time for a new challenge and would like to thank all the hard working staff at Nisa for their contribution over the years.”

Of her new role Jones said: “I am thrilled to be joining Conviviality at such an exciting time. It is a business with excellent potential and I look forward to working with Diana and the wider team to further grow the business and maximise the company’s strategic objectives and considerable business opportunity.”
