Lawyer Robert Bourgi said he handed over suitcases filled with cash between 1995 and 2005, including $10 million from the leaders of Senegal, Burkina Faso, Ivory Coast, Gabon and Republic of Congo for Chirac's 2002 presidential campaign.
Both Villepin and Chirac's lawyers denounced the claims.
The explosive allegations come as Chirac is on trial for unconnected corruption charges related to his years as Paris mayor, and as the campaign for next year's French presidential elections is heating up. The claims revived uncomfortable questions about France's cozy relations with autocratic regimes in its former African colonies.
