The Parliamentary probe into the alleged 'cash-for-vote' scam would begin tomorrow but it would not be able to seek evidence from members of the Rajya Sabha who have been named in the complaint.
The Enquiry Committee headed by senior Congress member V Kishore Chandra Deo will have its first meeting tomorrow.
Constituted by Lok Sabha Speaker Somnath Chatterjee last week, the seven-member committee is expected to decide on the procedure and modalities to be followed for the task which has to be completed by August 11.
Though it would be a preliminary meeting, the committee is expected collect evidence from the three BJP MPs -- Ashok Argal, Fagan Singh Kulaste and Mahavir Bhagora -- as also the television channel which conducted the sting operation, Lok Sabha sources said.
The Committee could also look into the original video footage and make transcript as part of its enquiry, they said.
In their petition seeking a probe into the charge that attempt was made to bribe them to get their support in the trust vote, the three MPs are believed to have named SP General Secretary Amar Singh and Ahmed Patel, Political Secretary to Congress President. Both members of Rajya Sabha had denied the charge.
However, sources said that the committee would not be able to collect evidence from members who belonged to the Rajya Sabha and if such a scenario, then the complaint would be referred to an appropriate committee of the Upper House.
