Kenya’s ministerial system has evolved significantly since independence in 1963, reflecting political transitions, constitutional reforms, and changing governance priorities. From the early post-independence cabinets under a parliamentary system to the modern structure of Cabinet Secretaries established by the 2010 Constitution, the composition and role of ministers have remained central to the country’s executive authority and public administration.

Kenya’s Ministerial System

At independence, Kenya adopted a Westminster-style parliamentary system in which ministers were drawn from Members of Parliament and appointed directly by the President or Prime Minister. Over time, executive power consolidated around the presidency, particularly after Kenya became a republic in 1964.

A defining milestone occurred with the promulgation of the Constitution of Kenya, 2010, which fundamentally restructured the executive arm of government. The new constitution replaced the traditional “ministers” with Cabinet Secretaries (CSs), who are no longer Members of Parliament and must undergo parliamentary vetting and approval before appointment. This reform strengthened separation of powers, accountability, and professionalization of the executive.

Key constitutional features include:

• Cabinet Secretaries are nominated by the President.
• Appointments require approval by the National Assembly.
• Cabinet Secretaries are individually and collectively accountable to the President and Parliament.
• The Cabinet may not exceed 22 members.

Prime Minister of Kenya

The office of the Prime Minister existed briefly during two historical periods:

• Jomo Kenyatta (1963–1964) under the pre-republic parliamentary system.
• Raila Amolo Odinga (2008–2013) under the Grand Coalition Government formed after the 2007–2008 post-election crisis.

Deputy Prime Minister

The position was created during the Grand Coalition Government to accommodate power-sharing arrangements. Notable holders included Musalia Mudavadi and Uhuru Kenyatta between 2008 and 2013.

Office of the President

The Office of the President has historically housed powerful ministries and ministers of state, particularly in areas related to national security, internal administration, and special programs.

Provincial Administration and National Security

This docket oversaw internal security, provincial governance, and coordination of national administration. It played a critical role during the one-party era and in maintaining internal stability.

The Ministry of Defence has been responsible for the Kenya Defence Forces, national security policy, and international military cooperation. Over the decades, it has gained prominence due to regional security challenges, peacekeeping missions, and counterterrorism operations.

Office of the Vice President / Deputy President

Before 2010, the Vice President often supervised several state ministries, including:
