May I add my words of appreciation to those of other hon. Members about the Government's approach of attempting to avoid escalating confrontation? Our concerns must primarily be about the personnel who have been taken. All that the House can do at this time is offer its full support to the Government, and unite to provide maximum support for the Government's endeavours. In addition, will my right hon. Friend say whether procedures have been reviewed to ensure that, as far as is practical, no ship can be isolated in such a way in future by any Iranian ship in the area?
