The Department of Field Support is also encouraged to co-sign the directive to ensure consistent guidance to all United Nations peacekeeping operations and relevant special political missions. 79. The General Assembly, particularly in the context of the work of the Fifth Committee, the Advisory Committee on Administrative and Budgetary Questions and the Special Committee on Peacekeeping Operations, should continue to support adequate budgetary provision for the deployment of child protection advisors to United Nations peacekeeping and political missions to ensure effective implementation of resolutions and mandates on child protection. 80.
