I can tell my hon. Friend that this is now not just the top priority for the Foreign Office, but something on which we are working together with our friends in the Ministry of Defence and the Department for International Development; my right hon. Friend Alistair Burt is a doubled-hatted Minister, serving both DFID and the Foreign Office, where he has charge of the crisis in Yemen. My hon. Friend Jeremy Lefroy will see increased British engagement on this issue throughout Whitehall.
