This policy brief is drawn from a research paper on Horizontal Accountability of the Executive to the Legislature in Africa: A Case of Kenya. Key questions revolved around: the mechanisms used by parliament to get information on the performance of the executive, responses to questions and requests for reports and statements, legislative outputs in terms of bills and types of bills and the work of PAC. The evidence gathered revealed gaps in the horizontal accountability of the Executive to the Legislature. This brief explains this and proposes a framework of optimizing horizontal accountability in the Kenyan parliament.
