High-profile (and high-charging) public relations firm Brunswick is investigating how a dossier containing confidential client information was left behind in a restaurant in London’s Covent Garden.

Brunswick, which specialises in helping large companies plan sensitive deals, has apologised for the security lapse. The firm’s clients include Marks & Spencer, Railtrack, British Telecommunications and thirty of the FTSE 100 companies.

Unfortunately for Brunswick, some of the dossier’s contents found their way into the hands of The Guardian newspaper. They suggest that the firm is preparing a deal involving Russian energy concern Gazprom, using the somewhat cloak-and-dagger codename Project Potemkin. Another operation, Project Sadler, is thought to refer to BT’s £3 billion sale of its stake in Japan Telecom to Vodafone.

True to its profession, Brunswick immediately embarked upon a damage limitation exercise, stating that the dossier contained no sensitive information, but was actually a press cuttings distribution list for advisers and clients.

Continued the firm: “We take this matter very seriously and our inquiry is continuing. We confirm that all public company transactions named in this list have already been announced and are therefore in the public domain.”
