India, Oct. 30 -- Union parliamentary affairs minister Kiren Rijiju on Friday responded to BJP MP Manoj Tiwari's dip in the Yamuna River with a challenge, floating the idea of a "swimming competition" between them.

Tiwari had on Thursday posted a video of him taking a dip in the Yamuna River, seemingly to point to the river's cleanliness, and had also invited Congress leader Rahul Gandhi and Aam Aadmi Party national convenor Arvind Kejriwal to do the same.

Replying to Tiwari's post, Rijiju wrote, "Manoj ji, don't you think that in Yamuna ji's much cleaner water, there could be a swimming competition between the two of us?" The exchange came amid efforts to clean the river, which flows for around 52 km through Delhi.
