The obligations for EDF to sell certain potential nuclear new build sites are as set out in the Sites Undertaking entered into between EDF and HM Government, copies of which were placed in the Library of the House on 24 September 2008. The European Commission as part of its clearance of the acquisition of British Energy has received certain undertakings from EDF that are slightly different from those agreed in the Sites Undertaking and these are as set out in the announcement of its decision on 22 December 2008. It is envisaged that when the Commission has published its full decision the Sites Undertaking will be amended to reflect these developments.
