The first such joint outreach to be attended by all Rajya Sabha and Lok Sabha MPs of non-NDA political parties is being organised in the Parliament annexe tomorrow evening.
The interactive session, the sources say, will see Ms Kumar, the opposition's presidential nominee, and Gandhi, its vice presidential candidate, make their presentations before them.
They will also answer any queries by MPs and engage with them in the closed-door interactive session, not open to the media.
While the election for the post of president will be held on July 17, that of the vice president, who is the chairman of Rajya Sabha, will be held on August 5.
Though the numbers are stacked in favour of the ruling dispensation, the opposition has made it a battle of ideologies.
As many as 17 non-NDA parties including the Congress, the Left parties, the TMC, BSP, SP, DMK, NCP, RJD, JMM JD-S and NC are supporting Kumar, while the JD(U) is supporting the NDA's nominee Ram Nath Kovind.
The JD(U) attended the meeting where Mr Gandhi was selected as the joint opposition vice presidential candidate. However, it is not clear whether its MPs will also attend tomorrow's meeting.
