NEW DELHI: Proceedings in both Houses of the Parliament were disrupted on the first day of the monsoon session on Monday as opposition protested over a host of issues, including farm laws and fuel price hike and even prevented PM Narendra Modi from introducing the newly-inducted Union ministers, a customary practice. Soon after Lok Sabha met at 11 am, four members who had won bypolls — Maddila Gurumoorthy (YSRCP), Mangal Suresh Angadi (BJP), M P Abdussamad Samadani (IUML) and Vijayakumar (Congress) — took oath as members. When Speaker Om Birla asked Modi to introduce the new ministers, leader of Congress in Lok Sabha Adhir Ranjan Chowdhury said his party had given notices to discuss issues including economy and (rising) prices. Members of Congress and TMC raised placards demanding the withdrawal of “black laws” on agriculture. Birla appealed to opposition members to not disrupt proceedings.
