Azimio leaders have accused President William Ruto of going against the judiciary and parliament.
The opposition leaders, led by Kalonzo Musyoka, accused the Kenya Kwanza Government of failing to keep promises made to Kenyans.
Speaking on Sunday at Makenji ACK Parish in Embu County, the leaders accused President Ruto of violating court orders and tampering with Parliamentary legislation.

"We will hold this government responsible in case our sons die in Haiti under the illegal deployment. We still oppose the move declared illegal by our courts," Kalonzo said.
"The government has failed to adhere to the Constitution that they were sworn in, to protect," he said.
The Wiper leader stated that the rising cost of living affects everyone, regardless of political beliefs.
DAP-K leader Eugene Wamalwa challenged Attorney General Justin Muturi to tell the government the truth about Haiti, just as he did about the housing tax.
He criticized the government's decision to deploy police to Haiti rather than addressing insecurity in Baringo and Isiolo counties, where teachers and an MCA were killed.
He pointed out that, according to United Nations regulations, one police officer should serve 450 people, but in Kenya, one officer should serve 1150.
Wamalwa stated that Azimio will lobby the government to reduce the high cost of living and taxes.
"The increased taxation of petrol and electricity is affecting all of us leading to high cost of basic items," he said.
