Tension began when Tirupur AIADMK MLA Gunasekaran picked at the opposition leader M K Stalin on his mass contact programme, ahead of the May assembly elections. Although Stalin and Durai Murugan were not present on the floor, their party challenged Gunasekharan and demanded that the speaker expunged his statement. The speaker, however, justified the latter's remark, but the party members were undeterred in their demand.
Meanwhile, Stalin arrived and a huge ruckus began. A few minutes into the debate and the Speaker asked the marshals to evict more than 80 DMK MLAs present in the house. In fact, Stalin was lifted and dropped in the lobby. According to a TOI report, Durai Murugan had passed out by then and the MLAs were seen reviving him.
Speaking to the media, Stalin later alleged that this was a got up case since speaker and leader of the house O Panneerselvam had conspired not to let the opposition interfere in the demands of the home department that fell under Jayalalithaa. The demands of the department were alleged to be moved to August 22 in the absence of the DMK leaders.
