Reyl & Cie

A cross-party group of French parliamentarians have reacted with outrage over the arrest and imprisonment in Switzerland earlier this month of French banker-turned-whistleblower Pierre Condamin-Gerbier (pictured), a former executive of the Geneva-based Reyl bank who has become a key witness to investigations into tax evasion in France via Swiss financial institutions. The lawmakers have joined with Mediapart in launching an initiative calling for the protection of whistleblowers and for Condamin-Gerbier's release from custody.

The still-unfolding scandal surrounding the secret foreign account of former budget minister Jérôme Cahuzac, first revealed by Mediapart last December, has rocked the French political establishment to its core. But it may not be the last such explosive revelation. For the private Geneva-based financial institution that Cahuzac used to manage his funds hidden abroad, Reyl & Cie, is alleged by several sources contacted by Mediapart to have provided its discreet services to other French personalities - including senior political figures.
