The Azimio coalition now calls for Trade Cabinet Secretary Moses Kuria's resignation after papers tied him to the oil scheme.

Documents in Citizen TV's possession show that, while there was no provision in the law requiring the Treasury CS to waive duty except for emergency relief goods, the Kenya Gazette Notice number Vol. CXXIV No. 250 was incorrectly used to import edible oils because the gazette notice itself covered the drought response initiative and not edible oils. It needs to be clarified why the taxman used the incorrect gazette notice.

Further evidence revealed that the Kenya National Trade Corporation used a single company to buy and sell the oil rather than importing it straight from the manufacturers in Malaysia or Indonesia.

Azimio claimed in a late-night statement that Kuria was using insults to cover up his blunders and that heads must roll.

The Azimio coalition also wants President William Ruto to come out and explain how much he knows about the issue and what action he plans to take against the individuals involved.

"Mr. William Ruto must address the country about what he knew about this scam and when he knew it, as well as what he intends to do about it."

"Heads have to roll. Someone must accept accountability. Take the lead and resign, CS Moses Kuria. "It cannot be business as usual to defraud suffering citizens and then go on a spree of abusing those same citizens whose monies have been stolen," the statement adds.

The opposition also demanded that the Kenya National Trading Corporation, which regulates the procurement, come clean and reveal whether they were compelled to swindle Kenyans.

"Azimio la Umoja is deeply disappointed, but not surprised, by what is now officially a grand scam by the Kenya Kwanza administration secretly ordering for duty-free importation of thousands of tonnes of cooking oil through the Kenya National Trading Corporation early this year," Azimio said.
