All India Anna Dravida Munnetra Kazhagam is a regional political party in Tamil Nadu state in India. The party was founded by M. G. Ramachandran and is now headed by J. Jayalalithaa. The party headquarters is in Royapettah, Chennai and was gifted to the party in 1986 by its former leader Janaki Ramachandran, wife of M. G. Ramachandran. The party was founded in October 17, 1972 by Maruthar Gopalamenon Ramachandran (popularly known as MGR), a veteran star of the Tamil film industry and a popular politician, as a breakaway from the Dravida Munnetra Kazhagam (DMK) led by M. Karunanidhi, the then chief minister, owing to differences between the two. Relations between the two parties have been marked by mutual contempt.
