Yoga guru Ramdev made the controversial comments at a Sadbhavna rally organised by the Rashtriya Swayamsevak Sangh (RSS) in Rohtak on Sunday.
The Congress and the Aam Aadmi Party today demanded action against yoga guru
Ramdev for his statement that he would have beheaded those who refused to chant 'Bharat Mata Ki Jai', had not the law of the land prevented him from do.
"Baba Ramdev's threat to 'cut heads off' at #RSS meet is a call to violent action and public intimidation. Mr Modi, await your action. Now!" Congress spokesman Sanjay Jha tweeted.
"Narendra Modi needs to tell India what action he will be taken against both Ramdev and the RSS," he added.
The yoga guru made the controversial comments at a Sadbhavna rally organised by the Rashtriya Swayamsevak Sangh (RSS) in Rohtak on Sunday.
Aam Aadmi Party leader Ashutosh said the yoga guru should be arrested.
"This man should be immediately arrested and sent to jail. Such people have no place in a civilised society," Mr Ashutosh said.
However, Communist Party of India-Marxist general secretary Sitaram Yechury dismissed the issue as a "diversionary tactic" of the Bharatiya Janata Party.
"Is 'Bharat Mata Ki Jai' an issue more important for the BJP than the issues of drought and farmers' suicides? It is just a tactic to divert (public) attention from the real issues," Mr Yechury said.
