On 29 July 2011, the Commission announced that it has decided to open an in-depth state aid investigation into UK measures to restructure Royal Mail. The UK intends to relieve Royal Mail of its pension deficit and to strengthen its balance sheet. The Commission is not currently convinced that the restructuring plan for Royal Mail provides for adequate measures to mitigate any distortions of competition brought about by the state intervention and to ensure a sufficient contribution by the company to the cost of restructuring. The Commission also has doubts whether the relief of the pension deficit can be justified on the basis that it is needed to relieve Royal Mail from an exceptional burden resulting from its past status as public sector monopoly.
