New Delhi, August 4 Congress MP from Ludhiana Ravneet Singh Bittu and Shiromani Akali Dal MP Harsimrat Badal on Wednesday engaged in a verbal spat outside Parliament over the issue of passage of farm laws. Both the Akali Dal and Punjab Congress MPs were standing outside Parliament protesting against farm Bills when suddenly Bittu and Badal started trading barbs over the issue of passage of the legislations. While Bittu accused Badal of aiding the passage of farm laws and being a part of the Cabinet that approved the Bills, the former union minister lashed out at Bittu saying the Congress walked out of the Lok Sabha and helped in the passing of Bills.
