"I am taking legal opinion to move a privilege motion in the Lok Sabha against Congress leader Mani Shankar Aiyar for his dirty barb against the prime minister," the Delhi BJP president said.
"The Congress leader is a confidant of the Gandhi family...Today's attack on the prime minister...seems to be an ultimate act of frustration in view of the impending defeat of the Congress in Gujarat," said Tiwari, who represents Northeast Delhi in Parliament.
"He (Modi) is 'neech kism ka aadmi' who has no 'sabhyata' (civility)," Aiyar said, attacking Modi after the latter accused the Congress of seeking votes in B R Ambedkar's name but trying to erase his contribution to nation building.
Congress leader Rahul Gandhi promptly admonished Aiyar, who has often courted controversy with his off-the-cuff comments, prompting the senior leader to apologise.
Modi, who was on campaign trail in the Patidar belt of Surat in poll-bound Gujarat, quickly seized on the comments, insisting he was targeted over his caste.
