The European Commission has opened a formal investigation procedure against France regarding the unlimited State guarantee provided to the French company La Poste. La Poste benefits from this guarantee because of its status as a legal entity governed by public law. The guarantee enables La Poste to obtain finance on more favourable terms than its competitors. The Commission had recommended the withdrawal of the guarantee for La Poste by the end of 2008. However, subsequent negotiations with France did not convince the Commission that the French proposals amounted to a termination of La Poste's guarantee. The opening of this in-depth investigation allows interested parties to submit their comments.
