Arputhammal, mother of one of the killers of Rajiv Gandhi, on Sunday urged political leaders not to impede the release of her son, A. G. Perarivalan.
Earlier, Dravida Munnetra Kazhagam (DMK) chief, Muthuvel Karunanidhi, said that the Chief Justice of India P. Sathasivam's indication would have a "political fallout" in Tamil Nadu due to the ongoing parliament polls.
Sathasivam had indicated that the court would pronounce its verdict on a petition for the release of all seven convicts serving life sentence before April 25.
"We have been making all arrangements with regard to the release of my son and at this time a leader suddenly commenting on the issue will confuse the entire matter. So we held this news conference and I now request all the concerned people not to disturb the path of release of my son anymore." Arputhammal said.
The Court commuted the death sentences on three men for their involvement in the killing of former prime minister Rajiv Gandhi to life imprisonment because of an 11-year delay in deciding on their petitions for mercy.
Gandhi was killed by Tamil suicide bomber while campaigning in an election in Sriperumbudur in May 1991.
The three men - tried as Santhan, Murugan, Perarivalan - members of a Sri Lankan ethnic Tamil separatist group, the Liberation Tigers of Tamil Eelam (LTTE). Gandhi's killing was seen as an act of retaliation after he sent Indian peacekeepers to Sri Lanka in 1987.
