From 1 February Read will step down from the WPP board to focus on his "increased executive responsibilities" for Wunderman. He will remain chief executive of WPP Digital. He was appointed to the additional role of global chairman at Wunderman in June last year but will relinquish that title. Morel will become the non-executive chairman of the agency network.
