A resolution should be passed by the Assembly urging the Centre to release the convicts -- V Sriharan alias Murugan, T Suthendraraja alias Santhan, A G Perarivalan alias Arivu, Jayakumar, Robert Payas, Ravichandran and Nalini, DK President K Veeramani told reporters here.
His suggestion for a resolution comes days after a rally was held in Chennai by pro-Tamil outfits and political parties pressing for release of the convicts on the ground that they had completed 25 years of jail term.
The Assembly had also passed resolutions on the issue in the previous house.
Former prime minister Rajiv Gandhi was assassinated by an LTTE suicide bomber on May 21, 1991 in Sriperumpudur near Chennai during an election rally.
Veeramani also urged the Centre to take immediate steps to rescue Sri Lankan Tamils stranded in Indonesia, and appealed to the UN to intervene and find a solution to the problem.
