The Office of the Deputy President is an office established under the Constitution of Kenya, 2010. Under Article 147, the Deputy President is the principal assistant to the President and deputises for the President in the execution of the President's functions. The Office derives its mandate from the Constitution, Executive Orders and other applicable laws.

The Deputy President serves as the principal assistant to the President and supports the President in the execution of Government functions. The Deputy President also undertakes functions assigned under the Constitution and other functions delegated by the President. The current mandate of the Office includes, inter alia, Chairing Cabinet Committees & coordination, intergovernmental relations, oversight of Cabinet decisions, public-sector reforms and coordination of development-partner programmes.

Article 147 of the Constitution provides that the Deputy President:
• Is the principal assistant to the President;
• Deputises for the President in the execution of the President's functions;
• Performs functions conferred by the Constitution and other functions assigned by the President; and
• Acts as President when the President is absent or temporarily incapacitated, subject to Article 134 and the constitutional provisions governing the exercise of presidential authority.
The Deputy President may not hold another State or public office.

The President may assign additional functions to the Deputy President in accordance with the Constitution. The current Government structure assigns the Office responsibilities including chairing Cabinet Committees, overseeing implementation of Cabinet decisions, coordinating relations between the National and County Governments, chairing the Intergovernmental Budget and Economic Council (IBEC), overseeing public-sector reforms and coordinating development-partner-funded programmes and projects.

The two offices are both part of the Presidency but have distinct mandates.
The Office of the Deputy President is constitutionally established. Its central role is to assist and deputise for the President and undertake constitutional and presidentially assigned functions
The Office of the Prime Cabinet Secretary (OPCS) is established through Executive Order and principally focuses on coordination and supervision of Government Ministries and State Departments, implementation of Government policies, programmes and projects, coordination of the National Government legislative agenda and oversight of National Government operations.

It would not be accurate to state categorically that one office has a universally "broader" mandate. The offices have different but complementary responsibilities.
