The Government will in no way pre-empt the decisions of those countries that have yet to ratify the Lisbon treaty. However, in light of the decisions at the December 2008 European Council, we will now work on all possible scenarios. This will include preparing for the possibility that the Lisbon treaty will come into force. We have a responsibility to engage in discussions to ensure that any institutional arrangements being planned for the event that the Lisbon treaty comes into force reflect our national interest. Not to do so would be irresponsible. I can, however, assure the House that work will remain on a contingency basis only and that no formal decisions will be taken unless and until the treaty enters into force.
