"Those who had worked with the intention of destroying a Tamil cultural event are maligning (our) efforts to revive it," he told reporters here.
Jallikattu was banned by the Environment Ministry in 2011 when UPA was in power at Centre, with the Supreme Court upholding that notification last year.
Singhvi had earlier tweeted: "Despite SC ban, Centre is trying to legalise jallikattu for political mileage in Tamil Nadu."
Only such a condemnation would mean that Congress' state unit was genuine about conducting jallikattu, he said in an apparent reference to Elangovan's insistence that steps should be taken for holding the sport.
If the TNCC did not condemn Singhvi, it would amount to 'betraying' Tamils, Radhakrishnan added.
The chorus for holding jallikattu, banned by the Supreme Court, has been increasing with various political parties in the state including Congress upping the ante on the issue.
Meanwhile, organisers and fans at Avaniapuram village in Madurai district have started invoking local temple deities seeking their blessing to revive the traditional bull taming sport, held during the Pongal festival every year.
Perumal, a temple priest, said organisers had come to the Ayyanar temple with a bull and prayed for revival of the sport.
