My right hon. Friend is right: we did foresee that this could be one of the reactions from the Iranian Government. That is why we took a number of steps after the detention in Gibraltar on 4 July, including the despatch of HMS Duncan and a lot of extra activity from HMS Montrose over the past few days in escorting 30 vessels, a number of which were British-flagged. There has been a lot of additional activity, but we wanted to do it in a way that was not a red rag to a bull and did not end up with even bigger consequences than the ones we faced, and that gave diplomatic channels a chance to work. I think that it was right to start in that way, but regrettably Iran has not chosen to follow the path that we hoped, and so that is why we are taking much more robust action today.
