In the second episode of Humanitarian Leadership Stories, our co-production with OCHA, the UN Humanitarian Office, top UN relief officials explain how the key humanitarian principle of putting people in crisis first – and remaining accountable to them – guides their work.

Daniel Johnson hears how UN humanitarian coordinators go about their work, taking calculated risks where armed groups are concerned, and not shying away from standing up to authority either.
