Situation in the Gulf

I can give the right hon. Gentleman a little bit of the answer to that, which is that it will not be a sudden switching on and off. There will be a gradual build-up of presence, because it takes time for ships to get to the region from all over the world. HMS Duncan will arrive on 29 July, or possibly even before that, as the first step in this process, but we are having substantive discussions later this week with allies from across the world in which things such as the timescales will become a lot clearer. I would be happy to write to him after that.
