Home Minister Rajnath Singh, Parliamentary Affairs Minister Ananth Kumar, Minister of State in PMO Jitendra Singh and top officials were to make presentations at the meeting.
The prevailing ground situation in Jammu and Kashmir, positions and views of different stake holders, individuals and groups were conveyed to the parliamentarians.
The exercise was undertaken to ensure that all MPs speak in tandem and there is consensus among the lawmakers while speaking to a cross-section of people, aiming to bring peace in the state, sources said.
The meeting is expected to take note about possible individuals and groups with whom the delegation may interact during its two-day tour beginning tomorrow.
