Allotting only seven seats to allies, AIADMK is contesting in 227 constituencies in the May 16 polls.
Though DMK is expected to contest 176 constituencies, today's launch of "Makkal DMDK," a breakaway group of DMDK steered by V C Chandrakumar, has led to speculation that it might get a few seats.
Chandrakumar, however, declined to spell out his outfit's stand categorically. "We will talk with DMK leadership if we are invited. I don't want to comment anything about contesting polls now," he told PTI.
DMK has allotted 58 seats to its allies - Congress (41), IUML (5), MMK (5), smaller parties, including Puthiya Tamizhagam (7).
