As chair of the all-party group for Yemen, yesterday I spoke to some very brave women from within Marib, which is under long-term siege from the Houthis. They told me that most of the Houthi forces are young men and teenage boys recruited from the most impoverished parts of Yemen. They also told me that Marib is now hosting over 2 million displaced people across 144 camps. Many children are not just suffering from famine and disease; they have been deeply traumatised after having been driven out by the Houthis. They all rely on generous UK aid and the example it sets to other countries who need to step up in the humanitarian aid effort and the subsequent reconstruction. How can indicating a cut in UK aid at this crucial time do anything but prolong this terrible conflict?
