Raila Odinga, the leader of the Azimio la Umoja Coalition, has demanded the immediate resignation of two cabinet ministers.
Indra stated on Monday that the Sh17 billion oil transaction required the resignation of Treasury Chief Njuguna Ndung'u and Energy Chief Davis Chirchir.
Raila claims that both of them have broken the law.
"CSs Davis Chirchir and Njuguna Ndung'u have gone against the constitution, committed criminal offenses, and abused office. They must not only resign but also be prosecuted," he said.
"Also, the Ministry of Energy and Petroleum must make public the Supplier Purchase Agreement signed with the oil companies," Raila said.
The leader of Azimio said that the government-to-government agreement was a plot to steal money from the public coffers in violation of the law.
Furthermore, Raila charged that the administration of President William Ruto was fabricating a lot of stories about the problems.
"We challenge the government to share evidence of the oil payments and show documents indicating when they were made, as well as bank accounts and recipients," he said.
In addition, Raila demands that the purported G-to-G oil arrangement's price manipulation, fuel contract transparency, and violations of consumer rights be looked into.
Senator Okiya Omtatah of Busia offered his opinion on the Sh17 billion oil scandal on Saturday and requested that two cabinet secretaries elucidate the true nature of the problem for Kenyans.
The lawmaker is calling on Chirchir and Murkomen to come up and be honest about what they know.
Businesswoman Ann Njeri Njoroge is at the centre of the Sh17 billion controversy.
She alleges that her oil, which was meant for Kenya, was improperly taken by the government.
She contended that while the government was emptying a ship carrying the oil at the Port of Mombasa, she was purportedly being held by state detectives.
Omtatah asserted, however, that there is more to the story and that the two CSs may be well knowledgeable about the matter they are keeping hidden from Kenyans.
