I thank the hon. Gentleman, too, for his co-operation and that of his colleagues. There is no indication of whether this is a one-off event, or of the significance that it might have. We are not aware of any change in the pattern of Iranian behaviour in the Gulf. Mr. Hague asked about the Iran nuclear file. The incident took place close to the vote in the Security Council but, I repeat, the Iranians have told us that they are not making a link between that and any other issue. I assure him and the House that that will make no difference to our determination. Indeed, it is a constant source of astonishment to me that it seems not to dawn on some of the authorities in Iran that behaving in that manner increases rather than diminishes people's concern about how they would behave if they had a nuclear weapon.
Mr. Moore asked me at what level we were operating. The answer is: at every level we can—official level and ministerial. Everywhere where there are levers to pull, we are pulling them. I am delighted to say that we have been offered wholehearted and strong support from our many allies to whom we have spoken. They have all expressed grave concern and been willing to try help in dealing with the Iranians. Indeed, they have done that.
