In a highly unusual move, Shell Brands International has announced the appointment of a third party to oversee the management of its £140 million ($240m; €204.5m) global media planning and buying operations.

The account, awarded in June of this year, is in the hands of Team Media for Shell - a dedicated WPP Group unit operating out of Mediacom's London office. It is responsible for Shell's global lubricants, retail and corporate campaigns.

But as of Friday all media-related activity undertaken by TMS will be overseen by Effective Media Management, a low-profile company specialising in the auditing of media planning and buying activities.

Says Shell Brands' chairman Raoul Pinnell: "We are delighted to welcome EMM as our global media auditing partner, and they will work closely with TMS to ensure that we are achieving the best value for money and efficiencies from our media planning and buying."
