Robin Young has stepped down as operations director at Mitchells & Butlers (M&B) after nearly three years with the group to return to his own consultancy company.

Susan Martindale has assumed responsibility for operations at the group, in addition to her full time role as group HR director, whilst the company’s conduct a “rigorous process” to select a replacement for Young.

It is thought that Young’s departure is part of a change in the group’s operations leadership now that its transformation plans are well underway.

Chief executive Alistair Darby said: “I would like to thank Robin for his significant contribution to M&B. His infectious enthusiasm, great sense of humour and people focus have been much appreciated. We wish Robin every success as he returns to his own consultancy business, as planned.”

Young joined the company in 2011 prior to which he worked for the government as chief operating officer at the nationalised arm of Bradford & Bingley. He has also worked at GlaxoSmithKline and Halifax.

His departure follows that of Tom Crowley, who left to join Giraffe; James Pavey, who left to join Tesco Family Dining; Adrian Frid, Miller & Carter retail director, who left to join Caffe Nero and. Tony Palmer, head of acquisitions, who left to join Bill’s.
