Kathiani MP Robert Mbui wants the government to hold senior officials responsible for the alleged fake fertiliser fiasco.
Mbui spoke on Monday during an interview with Citizen TV.
He said it should not be small players in the fiasco that should be held accountable, but rather, senior officials.
"A senior official should take the responsibility," he said.
He claimed the people currently being punished are junior officials and some business people.
Over the weekend, eight officials at the Kenya Bureau of Standards were reportedly suspended over the fake fertiliser fiasco.
They were reportedly suspended pending the ongoing probe into the matter by the Directorate of Criminal Investigations detectives and Parliament.
Officials said the eight were interdicted over the issuance of certification and marks of quality to two companies, which have been linked to the sub-standard fertiliser.
The eight were among those grilled by the DCI on Friday, Saturday and Sunday.
The DCI after completing investigations will forward the file to the DPP.
The Ministry of Agriculture said Friday they had completed the testing on all fertilisers being distributed under the subsidy programme.
A statement said all fertilisers being distributed meet the required quality requirements except those manufactured and distributed by one company that did not meet all required test parameters.
