The hon. Gentleman is making an excellent speech, particularly in his focus on education. I am the chair of the all-party parliamentary group on disability. Does he agree that in many developing countries, children with disabilities still find it too challenging to get to school and that we must focus on those extremely vulnerable children, who are often kept behind closed doors and never seen? We must ensure that they get every opportunity in life and that, in line with the sustainable development goals, we leave no one behind.
