She is also of the view that an expanded executive will enhance national cohesion and representation of regions at the helm of the country where major decisions are made.
Nyeri Governor Mutahi Kahiga told critics of the BBI process to join its proponents and fight from within.
“As a region, we must be in the BBI process. We have to join them and fight for the interests of our region while inside. We cannot fight for our welfare while outside the exercise; we must join them,” said Mr Kahiga.
His comments follow widespread fear that with the current system of governance, the region is likely to be out of the post-2022 government despite its numerical strength in voting.
The governors also condemned political formations in the region, saying this has led to physical confrontations, mainly in Nyeri and Murang’a counties.
In December, Mt Kenya leaders had planned a meeting to discuss and adopt a common position on the BBI report but it was cancelled at the last minute after politicians allied to Deputy President William Ruto scuttled the plan.
The meeting, called by Mt Kenya Foundation at Ole Sereni Hotel in Nairobi, was met with opposition from the Tangatanga group because the organisers were viewed as leaning towards the Kieleweke faction which enjoys State House backing.
Last week, ODM leader Raila Odinga held the first regional BBI consultative meeting in Kisii County, which marked the start of taking the discussion to the grassroots.
