legal course would be to secure the adoption of a further resolution" from the United Nations Security Council. Without such a resolution, in Goldsmith's opinion, invasion would still be legal under past resolutions 678 and 1441, if it could be proven that there were "strong factual grounds for concluding that Iraq has failed to take the final opportunity.

This last issue in particular was dealt with in more detail during campaigning over the following days. Further regional versions of Question Time aired the following day in Wales and Scotland, with the same format, where the leaders of Plaid Cymru and the SNP were
