The hon. Gentleman is very experienced. He is a distinguished former Chair of the Foreign Affairs Committee and his presence for this debate is extremely important.

People are starving. From looking at this problem from the outside, with a lot of knowledge about the tribal nature of Yemen, what does he think is stopping everyone saying that this has to end?
