The plot is said to be aimed at removing Maraga from office in a bid to weaken the Judiciary.
Led by National Assembly Minority leader John Mbadi, the leaders accused the Jubilee government led by President Uhuru Kenyatta and his deputy William Ruto of plotting to remove Maraga from office in a bid to weaken the Judiciary.
The move comes a day after the Jubilee Party Secretary General Raphael Tuju wrote a hard-hitting letter to Maraga accusing the judiciary of openly favouring NASA through unfavourable rulings in several crucial cases in what the Jubilee Secretary General termed as signs of "bias, impunity and poor leadership".

"With all due respect, may I state the following not to provoke you but to submit that no powers can be absolute. Irresponsible actions from the Judiciary, Executive or Parliament can burn this country," he said.
However, Mbadi said the increased personal attacks on judges and magistrates by the government was worrying and warned the vice must cease immediately in order to protect the independence of the Judiciary.
“Let them go directly to the point. We know they are targeting Maraga so that they have friendly people in the Judiciary,” Mbadi revealed.
On Thursday former CJ Willy Mutunga took issue with Tuju's letter saying it reflected the arrogance of political power and utter disrespect of the institution of Maraga as head of the Judiciary.
"Tuju should instead have directed his complaints to the Office of Judiciary Ombudsperson which processes complaints against judicial officers. He could have filed the complaint with the Judicial Service Commission. I believe his aim was to intimidate CJ Maraga personally," Mutunga wrote on Twitter.
After the Supreme Court led by Maraga annulled his August 8 victory last year, a visibly angry President Kenyatta said the country has "a problem" with its judiciary that must be fixed.
"We shall revisit this thing. We clearly have a problem," he said, referring to the judiciary. Who even elected you? Were you? We have a problem and we must fix it," Kenyatta stated.
