The focus of this paper is on the institutions outside the executive branch that include supreme audit institutions, legislative oversight bodies (such as parliamentary public accounts and budget committees, and ombudsmen), related independent bodies, and civil society organizations. Through their support for accountability, donor countries and international financial institutions seek to help countries: promote voice and accountability as an intrinsic human right, and improve development outcomes in terms of poverty reduction, sustainable development. The report is organized as: first, provide a brief literature review of research on accountability, and how donors and other actors can work to improve it, including a review of the experience of other bilateral and multilateral donors in supporting domestic accountability through their policies, strategies, and behaviors as well as through direct support to accountability actors and systems. Second, briefly review the guidance prepared for Bank staff toward enhancing accountability. Third, review some examples of the Bank's experience in supporting domestic accountability. Finally, we present some conclusions and accountability-related questions for further analysis.
