My right hon. Friend has made a calm, dignified and comprehensive statement to the House. Rightly, it was apologetic in parts, and I think that all reasonable people will thank him for that. However, when the smoke has cleared and we have moved on from issues to do with matelots and iPods, some questions will remain. Is my right hon. Friend entirely convinced in his own mind that the information that we had at the time about the map co-ordinates was correct, and that the Coventry's landing craft were not operating in Iranian waters?
