Lok Sabha Speaker Om Birla, dressed in a white track suit, led yoga day celebrations at Parliament premises on Friday.

Along with staffers, Parliamentary Affairs Minister Prahlad Joshi, BJP MPs Locket Chatterjee, Poonamben Maadam and Bhupendra Yadav, and former aviation minister Suresh Prabhu were among those who participated in the celebrations at the Parliament premises.

More than 400 people participated in the event which was conducted by two trainers from 7 am to 8 am.

Prime Minister Narendra Modi led the country-wide celebrations in Ranchi where around 40,000 enthusiasts stretched an extra muscle in various yogic exercises at the Prabhat Tara ground.

In Delhi, the celebrations played out at several venues -- from the sprawling Rajpath and the lawns of Red Fort to municipal parks, hospitals, gardens and offices with thousands of enthusiastic Delhiites performing asanas.
