The leaders of various political parties on Wednesday criticized MDMK founder Vaiko for celebrating the 60th birth anniversary of slain LTTE founder V. Prabhakaran.
BJP leader and former home secretary R.K. Singh condemned the move, saying it extremely wrong to do so.
"Prabhakaran and his organisation fought with our army, they killed our Prime Minister. It is a very wrong thing," he said.
Congress leader Ashwani Kumar called the move 'anti-national'.
"It is very unfortunate that in India someone is celebrating the birthday of Prabhakaran, who is known to have worked for the disintegration of the country and who is known to be a protagonist of terrorism to the pursuit of political goals," said Kumar.
"I think the nation as a whole must take a forthright stand. This is clearly an unacceptable activity in the country," he added.
According to reports, the MDMK supporters held meetings at various places remembering Prabhakaran's struggle for the cause of Tamilians.
