DMK President M Karunanidhi and VCK leader Thol Thirumavalvan clinched the deal under which the latter was allotted Tiruvallore (SC) constituency, a DMK release said.
VCK was earlier allotted Chidambaram (SC) seat, represented in the current Lok Sabha by Thirumavalavan himself.
The party cadre were dissatisfied over their party being given only one seat and one supporter had even allegedly tried self-immolation two days ago, which was criticised by Karunanidhi.
