Sir Julian Lewis: It is unusual for a terrorist group engaged in a civil war to invite retaliation of this sort by attacking international shipping so comprehensively. Clearly, the Houthis are acting as an agent of Iran. Can the Secretary of State advise us what the Government know about the ability of Iran to keep fuelling the attacks in the Red sea? Now that the domestic ability to manufacture drones in Yemen has been degraded, how easy will it be for Iran to supply them directly to the Houthis?

[The Secretary of State for Defence (John Healey): The short answer is that we must do what we can with allies to make it as hard as possible for Iran to maintain both its financial support to the Houthis and its logistical, munitions and military support and supplies. We are working on that with allies and, as I said to the House earlier, the straight military action that we were conducting last night is part of the solution for the long term. It is not the whole solution.]
