On Monday, DMDK MLAs V C Chandrakumar, K Nallathambi, D Murugesan, S Senthil Kumar, B Parthasarathy and R Arulselvan were suspended for allegedly assaulting C Michael Rayappan, one of the four MLAs from the Vijayakant-led party to have called on Chief Minister Jayalalithaa last year, much to the chagrin of the DMDK high command.
When the issue was raised by Opposition parties today, Jayalalithaa asked Speaker P Dhanapal to consider their plea.
However, unsatisfied with the Speaker's ruling, DMK members staged a walk-out.
