In episode four of Humanitarian Leadership Stories, a mini-series produced in collaboration with the UN Humanitarian Office, OCHA, we hear how tough discussions with warring sides are part and parcel of being a top UN relief coordinator.

This podcast also takes us to Nigeria, South Sudan, Jordan and Lebanon, where we’ll find out how the work of the UN’s relief chiefs is driven by putting vulnerable people first.
