AIADMK coordinator O. Panneerselvam and co-coordinator Edappadi K. Palaniswami on Sunday left for Delhi by two flights from Chennai and Coimbatore respectively.
Both the AIADMK leaders are likely to have a meeting with senior BJP leaders in the national capital on Monday.
Mr. Panneerselvam also called on Union Minister of State for Fisheries L. Murugan on Sunday.
The AIADMK has not released any official press release over their visit to Delhi.
The AIADMK and the BJP were in the same alliance when they contested the Assembly election early this year.
