A few months ago, Mwaura hit out at Sonko for exposing former Kibra MP the late Ken Okoth's hidden marital life during his requiem mass.

On Saturday, he accused the county boss of poor leadership, observing that he has been unable to deliver and is instead riding on personal appearance for mileage.

He took issue with Sonko's lifestyle, accusing him of engaging in cheap public relation stunts to remain relevant after failing to deliver his promises to Nairobians.

"Respect doesn't come from appearance but service to the citizen. You want to be seen to have vehicles, money and jewelry. These are people who lack a direction, they can't even believe they are leaders. (Heshima haitokani na vile unajibeba, ni vile unashughulikia Wanjiku. Wewe unataka uonekane eti uko na magari, pesa na bling bling. Hawa ni watu hawana mbele wala nyuma, hata wao wanashangaa hao ni viongozi)," he said on Radio Jambo's Mazungumzo Waziwazi show.

He wondered why the governor has even been sending his teams to help people outside the city yet he has not addressed the problems being faced by his own constituents.

"What are you doing when you leave your own disabled people here and head to Busia to offer help there? (Wakati unatoka hapa unaenda Busia eti kusaidia watu na unawacha walemavu hapa Nairobi unafanya nini?)," he added.
