I pay tribute to the hon. Gentleman’s close interest in this. I think there is no doubt—or very little doubt; we are close to certainty—that Iran was responsible. It is implausible and lacking in credibility for it to be suggested that the attacks came from the Houthi rebels. We certainly will co-ordinate with the United States as our closest military and security ally, but, as I have said, we actually need to send the broadest international response and signal to Iran if we are going to have the greatest degree of impact on its behaviour in the future, because Iran is relying on splitting and splintering the west, and indeed the other countries that it will fall back on and try to engage in partnership and alliance with as its isolation increases. We want to de-escalate, and the best way of achieving that effectively is to have the broadest international support with that goal in mind.
