The nine ODM MPs who met President William Ruto at State House, Nairobi, last week are expected to write to the party in three days to show cause why disciplinary action should not be taken against him.
Last week, Migori Senator Eddy Oketch requested the deregistration and expulsion of the nine MPs from the party for violating its constitution.
This prompted ODM National Chairperson John Mbadi to write a letter to the nine MPs, accusing them of violating Section 14A of the Political Parties Act, 2021 Article 11 of the party constitution and code of conduct.
"Your public display, conduct and general comportment not only violate Section 14A of the Political Parties Act, 2021 but also Article 11 of the party constitution and the party's Code of Conduct that you signed," said Mbadi.
ODM accused the MPs of trying to undermine their leader Raila Odinga after the party leadership publicly denounced the legitimacy of Ruto's presidency.
The President has within the period Parliament has been on recess met a section of ODM and Jubilee MPs, a move that has unsettled the Azimio leadership.
Some 30 Jubilee MPs have so far pledged to support President Ruto's administration including Nominated MP Sabina Chege and Eala legislator Kanini Kega.
Ms Chege is now facing ouster as the deputy Minority Whip for her recent political manoeuvres.
Jubilee Secretary General Jeremiah Kioni has vowed to oust Chege from the post arguing that Azimio will not give House leadership positions to those who have joined forces with Kenya Kwanza.
Kioni directed Azimio MPs to ensure the Nominated MP is de-whipped today as the House resumes sittings after long recess.
However, National Assembly Minority Leader Opiyo Wandayi said the matter of disciplinary action against any Azimio member in the National Assembly has not been brought to his office.
"We are going to wait until we get official petitions from whomever before we give it due consideration," said Wandayi.
Despite the migration of Jubilee MPs to Kenya Kwanza, Wandayi says that the party still remains a member of Azimio.
The National Assembly is expected to prioritise the supplementary budget, which seeks to reduce borrowing by Sh68 billion. Meanwhile, the Senate will deliberate on the revenue-sharing formula among counties.
The departmental committees will scrutinise the first supplementary budget submitted by the Treasury, with the aim of submitting their reports within two weeks.
Notable highlights of the supplementary budget include the introduction of a fuel subsidy dubbed "oil market price stabilisation" given that the budget for the Ministry of Petroleum increased by Sh41.7 billion.
Similarly, Department for Cooperatives is looking to get an additional Sh19.7 billion with a significant chunk of the funds going to the Hustler Fund.
Additionally, the MPs will consider the budget policy statement for 2023-2024, debate the debt management strategy for 2023, and propose establishing the Office of the Official Leader of the Opposition.
Several key legislative proposals are also in line, including a Bill to anchor the National Government Constituency Development Fund (NG-CDF) and the National Government Affirmative Fund in the Constitution, and the Finance Bill, which will outline the taxation policy of Kenya Kwanza administration.
