The no-confidence motion against Speaker Ramendra Chandra Debnath was jointly moved by the Congress and the Indigenous Nationalist Party of Tripura.

Discussion and voting on the motion is fixed for April 6.

The opposition had charged the speaker with playing a partisan role in the assembly and violating democratic norms and procedures in conducting the proceedings.

"The speaker had been curbing the democratic rights of the opposition members and violating the parliamentary practice and procedures," Leader of Opposition Ratan Lal Nath said.

This is for the first time in 15 years that the opposition members have brought a no-confidence motion against the speaker in Tripura.

The opposition leaders had earlier met Governor Dinesh Nandan Sahaya and complained about the alleged partisan role of the speaker.

The immediate provocation for the opposition to bring in the no-confidence motion was the decision by the speaker Monday to suspend Congress legislator Sudip Roy Barman for rushing near the podium to prevent Rural Development Minister Jitendra Chowdhury from delivering his speech.

He had also tried to hurl a chair at the speaker.
