The Opportunity us from God.
The analyst thinks lawyer asked Miguna should take the Nairobi Deputy Governor job as it is "an opportunity from God".
In a twitter post on Thursday, Mr Ngunyi, said: "To my friend Miguna, (Iif he is still my SMS friend). You should climb down, Miguna. The Sonko offer is an opportunity from God.
He added: "Genuine or not, take it. Then read Niccolo Machiavelli on how to impeach Sonko in 100 days of potholes and Nairobi filth."
Sonko had earlier indicated that Miguna is "anti-cartels #1" so he is the perfect fit for a capital plagued by corruption and a seemingly endless cycle of lack of basic services.
But in his response, Miguna told the analyst that he may have been to a school of comedy.
"My 'friend', Ngunyi, I didn't know that your 'Forthall School of Government' propaganda has now been transformed into the "School of Mystic Comedy."
He added: "Fortunately, I'm neither a student nor a teacher there. Best regards and cheers."
