I would gently remind the hon. Gentleman that we are not members of this coalition. We do not have locus in Yemen to undertake direct investigations ourselves. What we are talking about are alleged violations of international humanitarian law. The correct procedure when an incident has been brought to the attention of members of the coalition is for them to undertake the investigation itself. We are able to encourage and stimulate them to undertake that investigation, because there is a long-standing relationship between our respective armed forces. That is what we are doing, and that is the right way to proceed.
