Though Speaker G Karthikeyan sought to pacify the agitated members saying the issue could be discussed during zero hour, they persisted with their demand forcing the House to be adjourned temporarily within few minutes after question hour.
Kumar, who belongs to Kerala Congress (B), a single-MLA constituent of the ruling UDF, resigned late last night after his wife lodged a complaint against him in a police station.
Kumar, who had rejected his wife's allegation as "totally baseless" and even ruled out resigning from the ministry, however, tendered his resignation to the Chief Minister.
Sources in the Chief Minister's Office said the resignation letter will be forwarded to the Governor today.
The long-running family dispute reached a flashpoint yesterday with Kumar filing a divorce petition in a local court. Yamini had alleged that she had been a victim of domestic violence for the last 16 years and accused her husband of having "illicit affairs", while Kumar retorted saying he was a victim of "black mailing".
In the wake of embarrassment caused by the incident, the ruling UDF top leaders are said to have advised Kumar to quit leading to his resignation.
