The agency has entered into a redundancy consultation process with staff across the agency.
Porter Novelli UK MD Jean Wyllie said: ‘The redundancies are not in relation to client losses but from clients experiencing budget changes. Some of our clients have had a challenging year and the shape of their businesses is changing.'
Wyllie declined to say exactly how many staff would be made redundant.
PRWeek revealed earlier this year that Wyllie was leaving the agency without a job to go to (PRWeek, 9 September).
