Mr Odinga said a third tier of government would make devolution effective, arguing that some counties are not economically viable.
The number of governors will reduce from 47 to 14 and the devolved parliaments to 14, according to the proposal.
The Bomas draft had created 14 regions as the second tier and 73 districts as the third.
Orange Democratic Movement (ODM) leader Raila Odinga has stepped up the push for regional governments, a day after President Uhuru Kenyatta called for the amending of the Constitution.
And Mr Kenyatta’s statement on the eve of the 2010 Constitution’s 10th anniversary that “the moment to improve on it is now” sparked protests too.
