Derez, head of insurance company Covea, replaces Thierry Desmarest, who is stepping down after the Thursday board meeting, the sources said on Tuesday.

Fleuriot, who ran Credit Suisse's French operations for seven years, replaces Marc Ladreit de Lacharriere, who is set to retire from the board in June. Both appointments are to be submitted to the annual shareholder meeting the same month.

A Renault spokesman said the company had no comment.
