The Congress on Wednesday supported the demand of the Samajwadi Party and Rashtriya Janata Dal to ban the Rashtriya Swayamsevak Sangh (RSS).
Both parties earlier welcomed the lifting of the ban on SIMI.
"The RSS has been banned three times in the past and I do not think the demand to ban it again is unjustified," said Congress spokesmen Shakeel Ahmad.
His reaction came in the wake of both the SP and the RJD demanding a ban on organisations like the RSS and the Shiv Sena.
Ahmad, who is also a minister of state for home, clarified that he was speaking on behalf of the Congress party and not the government.
