Morrison leaves the agency after two years as global head of digital. He told PRWeek his new venture would focus on helping small marketing agencies improve the link between digital and integration.
'It's a matter of going and doing the new thing,' he said. 'I want to maintain my relationship with PR because I think PR agencies are well placed to pick up a lot of this work.'
Porter Novelli MD Jean Wyllie, who is also leaving the agency next month, said Morrison had made 'a huge impact on how we develop integrated campaigns for our clients'.
