Clark said he was saddened by Jamie’s departure, noting his contributions to the company will be a “lasting legacy”.
“He has been a huge support to me over many years, first in Europe and then over the past several years as CFO. His contributions to the development of our strategy, the delivery of our business capability programme, the building of our new business efficiency programme, and the strengthening of the finance functions will be a lasting legacy. He leaves the group in sound financial health, and we all wish him every success in the future,” Clark said.
