NEW DELHI: The Lok Sabha on Thursday witnessed a ruckus after Rahul Gandhi was interrupted during his speech on the energy crisis when he took a jibe at oil and gas minister Hardeep Puri for his name allegedly appearing in the files of an American sex-offender. He also attacked the govt over the US waiver to India to buy crude from Russia. “It has been a very puzzling fact why a nation the size of India would allow any other nation... the President of another nation to give us permission to buy Russian oil… I have figured the puzzle out. And the puzzle is about compromise,” he said and referred to Puri’s alleged link.This led to interruptions in the House, forcing Speaker Om Birla to intervene, saying the member cannot raise this issue, even as Gandhi insisted that he was speaking on energy and economic security. Later, opposition members entered the well of the House and Puri had to read out his statement amid sloganeering.
