Cotu secretary Francis Atwoli has contributed to the ongoing bribery allegations against MPs.
This is after MPs were allegedly bribed Sh10, 000 to shoot down a report on the contraband sugar.
Speaking on Tuesday, Atwoli said that the MPs were "cheap" and worse off compared to Koinange Street prostitutes.
"Afadhali wale watoto wetu wenye wanaenda Koinange usiku. Wanajitafutia chakula kuliko wabunge ambao hawana dignity mpaka wanahongwa na Sh10,000 (Our children who go to Koinange are better off. They feed themselves unlike an MP who goes to Parliament to get Sh10,000 bribes)," said Atwoli.
He made the remarks at the Trade Unions East Africa conference.
MPs allegedly received the bribes to shoot down the report that indicted Treasury CS Henry Rotich, his EAC counterpart Adan Mohamed and former Agriculture CS Willy Bett.
Speaker Justin Muturi has invited relevant authorities to investigate the matter that has been condemned by various leaders.
