Since 2011, UK funded governance programmes have supported reforms to budget processes in Yobe State in North-East Nigeria. This case study assesses contribution and impact of this support. It provides evidence on what reforms to budget processes took place, and how they occurred through a combination of political processes taking place in the state and support from UK programmes. The experience provides lessons on what has worked, what hasn’t and why. The analysis finds evidence of important improvements in budget processes in Yobe, which have taken place in a challenging context of protracted conflict and insecurity.
