Economist David Ndii has yet again hit at President Uhuru Kenyatta, accusing him of mismanagement of the country.
For years now, Ndii has been critical of Uhuru's leadership, often accusing him of over-borrowing.
The country currently is struggling to repay Sh6 trillion debt, most of it owed to the Communist Republic of China.
In a tweet on Sunday, Ndii insisted that Uhuru should have quit politics during retired President Daniel Moi's era which ended in 2002.
"Uhuru Kenyatta’s political career should have peaked at Minister for Culture and Sport in the Moi Government," he said.
Ndii has continued with onslaught against President Uhuru Kenyatta, and on Saturday, he questioned Uhuru's declaration about rice farming in Central Kenya.
"These are called roadside declarations. I hope he knows what he is talking about because farmers are paid for paddy, not rice. (takes 1.6kg of paddy to get a kg of rice). 85/= that would translate to Sh136 per kg of rice, "the renowned economist wrote.
"Mwea rice is retailing at Sh150/kg, meaning paddy at Sh136 leaves Sh14 margin for processing transport, distribution. Untenable," he added.
