"The right-wing groups have been demanding since long to make 'Vande Mataram' the national anthem. So, don't be sure that 'Jana Gana Mana' will remain national anthem forever," Sarkar, a former JNU professor, told students at the varsity.
Sarkar was fifth lecturer in the series of the "nationalism" open-air lectures, organised at the varsity in protest of the branding of the university as "anti-national" in wake of an event against hanging of Parliament attack convict Afzal Guru.
Member of Parliament and former education minister of Kerala E T Mohammed Basheer, said the agitation in JNU was not just about the particular university but about the nation.
"The government wants to attack the entire country by attacking autonomy of institutions, This agitation is not just for JNU but for the entire nation," he said.
