On Thursday, a total of 86 MCAs — 47 from ODM and 39 from Jubilee — appended their signature to the notice of impeachment motion against a threshold of only 42 MCAs.
Two-thirds, or 82 out of the 122 MCAs, will be needed to vote in support of the motion on Thursday for it to sail through.
Embattled Nairobi Governor Mike Sonko has dismissed a fresh attempt to impeach him as premature, saying the court is yet to rule on a petition filed against a similar motion lodged by Minority Whip Peter Imwatok in February.
The governor, through lawyer Harrison Kinyanjui, told assembly Speaker Benson Mutura that Justice Byram Onganya had on October 23 dismissed a preliminary objection to the petition.
