Rahul, who always sits in the back benches, stood on the aisle joining other Congress and Opposition members who stormed the Well, disrupting normal business of the House.
Opposition members continued slogan shouting against hike in prices of food as well as petrol, diesel and LPG besides rail fare hike and Rahul stood in the aisle during the entire period.
Slogans like "achha din ayega, mahangai badhayega (good days will come, prices will rise)" and 'roll back rail fare hike' were heard in the House.
When the Congress leader was taking part in protests, his mother and Congress President Sonia Gandhi was in her seat in the front row.
During the protests, Rahul was seen talking to NCP member Supriya Sule and Trinamool Congress leader Saugata Roy.
Rahul had taken part only in a few debates, including discussions on Lokpal Bill, in the last Lok Sabha.
He had also reportedly refused to take the responsibility of leader of the Congress Parliament Party.
BJP leader Rajiv Pratap Rudy took a swipe at Rahul saying the Congress leader has become more active after his party came into Opposition.
