The situation my hon. Friend describes in Marib is deeply concerning. We have called on the Houthis to end their assault. Marib has become the temporary home for many internally displaced people, and the situation there is dire. A number of people have mentioned our support for, or our relationship with, neighbouring countries, and of course defending Marib against this Houthi assault is part of the conversations we have. But, ultimately, the best thing we can do is bring about a swift end to this conflict.
