John McFarlane, chairman of Aviva, said: "I am delighted we have secured Mark for Aviva. His leadership credentials are incredibly strong. He has an outstanding track record of leading a major insurer, of transforming its performance and culture, of implementing a growth agenda and of producing significant shareholder value, all of which are essential for Aviva's success going forward."
