While discussing the issue of illegal immigrants in the state and absence of a deportation agreement with Bangladesh, Congress MLA Sherman Ali Ahmed used a word to describe the prime minister.
Ruling MLAs immediately rose to their feet and objected to the word, but Congress legislators defended it saying it was relevant.
BJP MLA and the party's state unit president Ranjeet Kumar Dass urged the speaker to expunge the word from the record.
Accepting the request, Speaker Hitendra Nath Goswami expunged the word from record.
Earlier, former Chief Minister Prafulla Kumar Mahanta asked the government to re-adopt an old resolution accepting 1971 instead of 1951 as base year for deporting illegal immigrants from the state.
Parliamentary Affairs Minister Chandra Mohan Patowary said 33 persons have been detected and deported during 2016-17.
