All nice except you're are looking for a system where PM is not a glorified Duale but true head of gov and PORK is only the head of state. Nobody in kenya is proposing that. The fear of two centers of powers and the fear of unaccountable PM (elected only by some bribed or compromised Mps) works against parliamentary system. Tell you what parliamentary system really only work in Europe with morachies - kings - otherwise in africa - it will be civil war btw PORK and PM - unless one is clearly subservient - a glorified Duale.
It very likely we will move from
US pure presidential to French semi-presidential system - if Raila can surmount the hurdles. Those hurdles are not easy.
Nobody buying parliamentary system in Kenya with Mpigs enjoying such a reputation.
Republican forms of government:
Blue-Presidential republics with an executive presidency separate from the legislature
Yellow-Semi-presidential system with both an executive presidency and a separate head of government that leads the rest of the executive, who is appointed by the president and accountable to the legislature
Orange- Parliamentary republics with a ceremonial and non-executive president, where a separate head of government leads the executive and is dependent on the confidence of the legislature
Republics with an executive presidency elected by the legislature
Actually several parties, governors and NGOs proposed it. E.g. Chap Chap wants PM to be majority or coalition leader -"appointed" by PORK, forms and runs cabinet, fired by 2/3. Haji has 100+ presentations from churches, NGOs and the shebang. This one-man-one-vote and PORK appointing PM has emerged suddenly to counter Ruto and Kuria propaganda that Gema will be shortchanged.
Of course we all know BBI is an orchestra that sing Uhuru song.
