The Ministry of Parliamentary Affairs is one of the specialised Ministries, set-up under Section 11 of the Parliamentary Service Act (Act 460), with the main purpose of deepening good governance. It was the main link between the Executive and the Legislature. The Ministry was proscribed in 2009.

The Ministry of Parliamentary Affairs was recreated in January 2017 through Executive Instrument 28 (EI. 28) and is mandated to initiate policies to coordinate, facilitate and evaluate the effective and efficient management of government business on the floor of Parliament, as well as report on it for good governance.
