Heathrow (Third Runway)

Further to the reply that the Secretary of State gave to my hon. Friend the Member for Morley and Rothwell (Colin Challen), can we be clear? What the Government have said in the context of the new planning legislation is that a national policy statement will be produced as a result of consultation, there will be a Committee examination of that, and there will be a debate in the House on the motion. But no guarantee is given by Government that that resolution will determine the national policy statement. It could be a debate on the Adjournment of the House, not to determine the policy. May we have an assurance that it will determine the national policy statement?
