"The Tamil Nadu Governor should immediately implement (the cabinet decision) to bring joy to the people," DMK president M K Stalin told reporters here.
Besides DMK, the PMK and AMMK were among those who hailed the move.
Stalin recalled his party's earlier demand that the state cabinet adopt a resolution for release of the convicts in the wake of the Supreme Court asking Governor Banwarilal Purohit to consider the mercy petition of one of them, AG Perarivalan, seeking remission or pardon under Article 161 of the Constitution.
The K Palaniswami-led state cabinet met here Sunday where a decision was taken to recommend to the Governor, the release of V Sriharan alias Murugan, T Suthanthiraraja alias Santhan, AG Perarivalan alias Arivu, Jayakumar, Robert Payas and Nalini, all serving life imprisonment.
However, TNCC President Su Thirunavukkarasar wanted the Governor to toe the Centre's earlier line, where it had opposed Tamil Nadu government's previous proposal for the release of the convicts.
"It is true that they have been in prison for a long time. But their release will set a wrong precedent. Law is common for all. If you take decisions based on (factors like) mercy, it will set wrong precedent in the future," he said.
PMK founder-leader S Ramadoss welcomed the move, saying the decision was not merely that of the cabinet but reflected that of the state.
He urged the Governor to "implement" the cabinet recommendation without any delay.
"The Governor should not make a controversy out of the Cabinet's recommendation and accept it and order for the release of all seven Tamils," he said in a statement.
AMMK leader TTV Dhinakaran also urged the Governor to approve the state cabinet's decision.
Mother of Perarivalan, Arputhammal, welcomed the government's decision and said there should be no politics over it.
She met Palaniswami here and thanked him for the cabinet decision.
Later, she told reporters she was "relieved" her son would 'reach' her after a long time.
"This is historic. We were not aware how the years of struggle would end. He (Perarivalan) was 19 when he went to jail (in 1991)," she said.
Former prime minister Rajiv Gandhi was assassinated on May 21, 1991 at Sriperumbudur near here by an LTTE woman suicide bomber, Dhanu, at an election rally. Fourteen others, including Dhanu herself, were also killed.
After the state government passed a resolution on Sunday to free all the seven convicts in Rajiv Gandhi assassination case politicians across the state have demanded their immediate release.
DMK president MK Stalin said that after the Supreme Court direction to state government to pass a resolution on the release of seven convicts and hand it over to the Governor, the DMK had demanded state to pass a resolution.
The state too passed the resolution in the Cabinet meeting on Sunday and now Governor Banwarilal Purohit should not waste time on the resolution.
“Governor should act swiftly on the resolution and should bring smiles on the faces of Tamil people,” said Stalin.
Release Rajiv convicts in a day or two: Leaders
R Mutharasan, state secretary, CPI, said that based on the Supreme Court direction the state government had passed unanimous resolution to free all the seven convicts in Rajiv Gandhi assassination case and the Governor should not waste time on it. “All the seven convicts had spent 27 years in prison and so Governor should immediately accept the resolution passed by the state government,” said Mutharasan.
VCK leader Thol Thirumavalavan welcomed the resolution. “Release of seven convicts is the long term demand of Tamil people and state government should be thanked for passing the resolution on their release,” he said.
K Balakrishnan, state secretary, CPM, said that the demand to release all seven convicts in Rajiv Gandhi assassination case had been made for long and due to Supreme Court and the Central government the decision to release them had been dragged for several years.
“However, the Supreme Court, on September 6, had directed the Governor to take decision on their release based on the recommendation of the state. Now the Governor should immediately release the convicts within a day or two. There is no need to further consult any legal experts as the Supreme Court has laid down the directions clearly, said Balakrishnan.
