SP chief Akhilesh Yadav, in an apparent dig at UP CM Yogi Adityanath, said that before challenging others, people should dare sip water from Yamuna which flows through Mathura in UP. This comes after CM Yogi said he took a dip at Triveni Sangam during Maha Kumbh Mela and challenged AAP chief Arvind Kejriwal to take a dip in Yamuna.
