David Watt, managing director of marketing communications agency Corporate Innovations, said: "I am confident that Peter's experience and direction will prove a real asset to the organisation and reflect our commitment to achieving our long-term ambitions.
"Peter has proven real-world know-how in building agencies that deliver outstanding work to their clients, and we hope that he can further enhance the work that our fantastic team are already producing. We have previously worked with Peter on collaboration projects and I think it’s fair to say that we both liked what we saw and wanted to do more together."
