He rejoined the agency in February as chief executive after a gap of 17 years. During that time he had served as group chief executive at Grayling and a short three-month period at Gardant Communications before leaving earlier this year.
Communication Group co-founder and deputy chairman Peter Hamilton confirmed Kennedy’s exit, saying: ‘Nigel’s departure is perfectly amicable, unfortunately it just hasn’t worked out as he and we would have wanted.'
It is not thought Kennedy is leaving for a specific role, although he will continue his various non-executive positions. He is understood to have left the agency around two weeks ago.
Kennedy could not be reached for comment.
The Communication Group is not directly replacing his role. Emma Johnson, MD, corporate affairs, has become chairman of the agency’s management board and will effectively run the company day-to-day alongside chairman Maureen Smith and deputy-chairman Hamilton.
Kennedy left Grayling in December 2009 after the Huntsworth-owned company was restructured to combine it with sister PR brands Trimedia and Mmd. He re-emerged at Gardant in October 2010 as a partner.
