"Law and order comes within the purview of the state government and hence Tamil Nadu Government has taken the right step to deny permission for the meeting by the Naam Tamizhar Katchi yesterday," he told reporters here.
Narayanasamy said it was wrong on the part of the Naam Tamizhar Katchi to go in for a meeting by displaying photos of slain LTTE leader Prabhakaran.
The Centre would intervene and take action in the larger interest of national unity and integrity if it found that any outfit's activities were a threat to national sovereignty, Narayanasamy said.
Police had withdrawn permission granted to the outfit headed by film director Seeman to hold the meeting at Cuddalore in Tamil Nadu in support of the demand for separate Tamil Eelam as the organisers had violated certain conditions.
Former ally of the Congress, DMK chief Karunanidhi has disapproved of the ban.
