Bharatiya Janata Party leader Subramanian Swamy today termed Rahul Gandhi's hug to Prime Minister Narendra Modi a 'childish act' and said Parliament will become a 'chaotic place' if other members also start doing so.

"It was very juvenile behaviour and if everybody starts doing so then Parliament will become a chaotic place. The Lok Sabha Speaker is right as decorum has to be maintained in the House," Swamy told reporters on the sidelines of an event.

After a no-holds barred and scathing criticism of Modi on several issues including Rafale jet deal, Congress president Rahul Gandhi walked across to the prime minister and hugged him, a gesture which took the Lok Sabha members by surprise.

Modi, who initially looked nonplussed and did not stand up to hug him, recovered quickly and called Gandhi back and patted him on the back.

"This is what it means to be a Hindu," Gandhi said after coming back to his seat amid a big applause from his party members, including his mother Sonia Gandhi and other leaders present.  -- PTI
