The advisory board constituted by the Tamil Nadu government met her at the Vellore central prison to consider her premature release on Wednesday, Jan 20.
According to reports, this is the first time that government appointed board has recommended a premature release of Nalini.
However, sources said the Centre and the Tamil Nadu Congress leaders are not in favour of releasing Nalini.
Prime Minister Manmohan Singh, UPA Chairperson Sonia Gandhi and core group members from the Congress are set to meet on the issue.
Earlier, when Nalini's premature release plea was rejected by state constituted board, she then moved to Madras High Court against the decision complaining about the structure of the board.
HC then directed the government to constitute a new advisory board.
