Prime Minister Narendra Modi and Congress chief Mallikarjun Kharge were seen sharing a brief, friendly exchange as leaders came together at Prerna Sthal in the Parliament complex to honour Dr BR Ambedkar on his 135th birth anniversary.
Modi and Kharge were seen greeting each other and smiling during a short interaction, before shaking hands and speaking briefly.
The two leaders were then seen laughing together in what was a rare moment caught on camera.
Both leaders paid their respects to Ambedkar, with Modi leading members of Parliament and others in offering floral tributes in the Parliament complex.
Kharge called Ambedkar a visionary who gave India its 'moral and Constitutional soul' and urged people to protect the principles laid down in the Constitution.
