A National Assembly of 349 and a Senate of 67: how the 2010 Constitution rebuilt Kenya's Parliament

Background

Article 93(1) of Kenya's Constitution establishes a bicameral Parliament made up of the National Assembly and the Senate.
The National Assembly has 349 members, with the Speaker as an ex officio member.
The Senate has 67 members, with the Speaker as an ex officio member.
The Senate represents the counties and protects county interests, decides how national revenue is shared among counties, and takes part in the impeachment of the President and Deputy President.
Chapter Twelve of the Constitution creates 47 county governments, each with a County Assembly and a County Executive.
Bills affecting counties must be considered by both chambers; bills that do not concern counties go only to the National Assembly.
At independence Kenya had a Senate and a House of Representatives, but amendments between 1964 and 1968 merged them, leaving a single chamber until the 2010 Constitution restored two chambers from 2013.
