Last week, it was reported that De Pouzilhac was set to resign from Havas and be replaced by Jean-Marie Dru, chief executive of TBWA\.
French daily La Tribune reports today that Dru is close to signing a deal to take over as chief executive of Havas, endorsed by Vincent Bollore.
If De Pouzilhac does go, he is expected to step down but stay on in an advisory role at the company.
Havas is refusing to comment ahead of today's meeting, which is due to take place at 2pm UK time.
The fevered speculation has been stoked as Bollore continues to cement his growing influence at Havas, where he now controls 26% of the company.
De Pouzilhac had long opposed Bollore's move and it had been widely thought that he would step down if Bollore was successful.
