According to Marc Mendoza, the chief executive of MPG UK, Offen, 48, will continue to work two days a week for the network, in a part-time consultancy role.
Offen, a former chief executive of MPG UK, took the network job at the beginning of 2003. Mendoza said there were no plans for a successor.
In 1989, Offen split Euro RSCG's media department and created a media agency, Mediastar, to compete with the media independents.
In 1996, he launched Media-polis, which added the media billings for WCRS and Young & Rubicam, and three years later the agency joined the Havas-owned MPG network.
Strong in Latin America, France and Spain, the MPG network is considered to have a patchy global spread. There is uncertainty over its future following Havas' failure in its bid for Grey Global, which would have hitched MPG to Grey's MediaCom network.
