Nalini, the life convict in the Rajiv Gandhi assassination case, on Saturday met her husband and a death row convict in the same case, Murugan, at the Vellore prison, jail sources said.
The meeting, lasting 20 minutes, is the first between the couple, after Murugan's clemency petition was rejected by President Pratibha Patil last month.
Nalini was shifted to high security Vellore prison on Wednesday from Puzhal Jail in Chennai.
The Tamil Nadu Assembly on August 30 had passed a "unanimous" resolution requesting the president to reconsider and commute the death sentence awarded to the three convicts -- Murugan, Santhan and Perarivalan -- all lodged in Vellore jail.
The Madras high court, too, the same day stayed the execution of the accused for eight weeks, which was earlier scheduled for September 9.
Nalini was also awarded the death sentence in the former prime minister's assassination case but it was commuted to life.
