He played a key role in the deleveraging plan and the wider transformation of the Group including the ‘Fit for Growth’ programme. We wish him well for the future.”  

Mark Whiteling added: “It has been a great pleasure to work alongside Debbie and the Executive team, as well as colleagues across the company. I am proud of the work we have achieved strengthening Interserve’s balance sheet and ensuring that the company has strong foundations for the future.”
