Secular Progressive Alliance

Tamil Nadu The Left parties defected to the All India Anna Dravida Munnetra Kazhagam (AIADMK)-led front in 2009 after it withdrew support to the Congress-led United Progressive Alliance coalition in the Centre.

The Pattali Makkal Katchi withdrew support in 2008 over differences with the DMK but it still remained in the Congress-led UPA in the Centre.

But after differences of seat sharing before the 15th Lok Sabha, it withdrew support to the UPA also and crossed over to the AIADMK-led front.

The Manithaneya Makkal Katchi was formed in 2009 by the Tamil Nadu Muslim Munnetra Kazagham and immediately joined the DPA.

The MMK withdrew from the DPA and as of now tied up with small parties like actor Sarath Kumar-led Akila Indiya Samathuva Makkal Katchi, the Puthiya Tamilzhagam and the Bharatiya Janata Party (BJP).
