Kenya's MPs are mostly dishonest, insincere and tribalistic, says speaker of parliament Francis ole Kaparo.
Parliament often does not have a quorum to pass business
"There is clear lack of clarity, purpose, and vision in the behaviour of our MPs and political parties," Mr Kaparo told a meeting of young MPs.
He went on to reprimand them for failing to turn up to work, which meant the chamber was unable to pass laws.
A recent survey revealed that parliament was open for business for only 57 days last year.
Mr Kaparo, one of Kenya's longest-serving MPs, likened his colleagues to local councillors, concerned only with petty and selfish interests.
"If you want to talk about parochial issues, you'd rather go back to the councils," Mr Kaparo is quoted by Kenya's Daily Nation newspaper as saying.
On occassion as few as five MPs attend debates when a quorum of 30 is needed to pass bills, the newspaper reports.
Mr Kaparo also expressed concern that MPs showed no party loyalty, with many leaving the former ruling party Kanu to join the governing Narc coalition which came into power in 2002.
"They no longer have any cause and do not espouse any ideology,"he said.
The BBC's Caroline Karobia in Nairobi said many people in the capital agreed with the speaker's comments, regarding their parliamentarians as lazy.
It was difficult to find anyone who had a good word to say about MPs, she said.
