My Lords, I can confirm that our delegation in York has been working extremely hard to forge agreement on the way forward for nuclear disarmament and non-proliferation. In particular, it has made a major effort to bridge our remaining differences with the countries which make up the New Agenda Coalition. We have shown a good deal of flexibility and imagination in seeking an agreed outcome from this conference and we hope that others will do likewise. I am sure that the whole House will join with me in expressing the hope that these efforts will bear fruit. If agreement is not reached by the time the conference ends tomorrow, it will not have been for any want of effort on our part.
