Jacobs’s departure comes just four months after that of chief financial officer Dana Mulvihill. She left to return to her native Ireland in January.
Jacobs, Mulvihill and FD chief executive Charles Watson ran FD’s international network. Mulvihill and Jacobs worked on the management buyout of FD from Cordiant last year.
Jacobs said he decided to leave FD to finish a novel he has been working on. ‘I intend to be living proof that there is life after PR,’ he said.
FD London chief operating officer Tim Spratt said the firm had yet to appoint a replacement for Jacobs. ‘How we allocate the role in the future remains to be seen,’ he said. Spratt added that Jacobs’s clients would be split among FD’s practice groups.
Jacobs joined FD in 1987, shortly after the financial PR firm was founded.
Earlier this month, FD appointed its first advisory board, whose members included Barclays chairman Sir Peter Middleton (PRWeek, 9 April).
