I admit that I look at this from a slightly different perspective. We are launching a missile in self-defence at an incoming attack vehicle, which is attempting to hit something behind us, which is probably worth half a billion pounds and well in excess of 100 lives. Having moved into position, there is no question that we are doing absolutely the right thing in deterring, degrading and reducing the Houthis’ effectiveness. On lessons from Ukraine, I assure the House that there is an enormous amount of activity going on in precisely that area, about what action can be taken to update and diversify all the weaponry at our disposal.
