Dr Mike Clarke is to become the RSPB’s new chief executive, taking over from Sir Graham Wynne, who is leaving after 23 years in senior management at the charity. Dr Clarke is currently the RSPB’s director of operations and he will take up his new role in late May. He said: “The RSPB is in great shape to tackle the challenges the natural world faces, and let’s not be under any illusion, they are huge.”
