Mike Waterson, Chairman of Warc and a close friend, said:

"We have lost one of the most influential advertising industry practitioners and thought leaders of his generation. Effortlessly wise, with a formidable intellect coupled with an acerbic sense of humour, and unfailing generosity to all, he will be sorely missed."
