Director of communications Marie-Laure Simon-Beaulieu has been promoted to the post of chief of staff to Alain Juppe, the former PM who heads the UMP with Xavier Schallebaum, taking over as comms director.
The party is preparing for four elections, most notably to the European Parliament.
It has created additional PR-related posts covering European affairs and international affairs.
The UMP says that at least two of the posts will go to women, as the ruling party has pledged to open up more positions to French women.
The UMP backed rival RPR leader Jacques Chirac to be re-elected as President two years ago with a landslide win over National Front leader Jean-Marie Le Pen.
