The Orange Democratic Movement party has made a final resolution on working with Jubilee.
ODM chairman John Mbadi has announced that his party will support Jubilee's Big Four agenda.
Speaking in parlaiment, Mbadi said that ODM will not allow NASA partners to blackmail leader Raila Odinga.
Mbadi made the remarks on Wednesday afternoon during the debate in parliament on the partnership between President Uhuru Kenyatta.
The debate comes after Raila held talks with President Uhuru Kenyatta on Friday last week.
The two leaders agreed to bury the hatchet and work towards pushing for National unity following months of political tension.
However, NASA co-principals have accused Raila of acting selfishly by meeting Uhuru alone without any consultation.
