Prime Minister Narendra Modi on Tuesday asked NDA MPs to follow parliamentary rules and conduct, and learn from senior members about the best practices, comments that came a day after the ruling alliance accused Leader of Opposition Rahul Gandhi of making a “most irresponsible” speech.

Addressing a meeting of NDA MPs, Modi said the opposition is upset as for the first time a non-Congress leader, that too a “chai-wala”, has become prime minister for a third straight term, sources said.

Highlighting his humble origins, he took an apparent jibe at the Nehru-Gandhi family saying that its members used to be prime minister and gave little recognition to those from outside their fold, the sources said.

Briefing reporters, Parliamentary Affairs Minister Kiren Rijiju said Modi asked MPs to study parliamentary issues, attend Parliament regularly and raise the matters related to their constituency effectively.

Asked if Modi referred to Gandhi’s Monday speech in Lok Sabha, Rijiju said he made no such mention but added that when the country’s prime minister speaks, the message is for everyone.

Union minister and Lok Janshakti Party leader Chirag Paswan told reporters that NDA members were concerned over Gandhi’s “personal attacks” on Modi and Speaker Om Birla and his remarks which hurt the feelings of the followers of different religions.
