Withdrawals

The Left parties defected to the All India Anna Dravida Munnetra Kazhagam (AIADMK)-led front in 2009 after it withdrew support to the Indian National 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 over 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. However, before the Lok Sabha elections, its demand for two Lok Sabha seats and one Rajya Sabha seat was turned down by the DMK, which offered them a lone Lok Sabha seat. The MMK withdrew from the DPA, and is 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).

Prior to the 2026 Tamil Nadu Legislative Assembly election, the Tamilaga Vazhvurimai Katchi and Moovendar Munnetra Kazhagam withdrew their support from the SPA alliance. Following the election, the Indian National Congress, which had won five seats as part of the SPA alliance, extended its support to Tamilaga Vettri Kazhagam. The Communist Party of India, Communist Party of India (Marxist), Viduthalai Chiruthaigal Katchi and Indian Union Muslim League also extended unconditional support to TVK to facilitate the formation of a government before the deadline (10 May) and avoid the imposition of President's rule, while continuing their alliance with the DMK-led SPA. Subsequently, the IUML and VCK joined the TVK-led coalition government, with their MLAs being sworn in as ministers. The parties also formally confirmed that they would continue as part of the SPA alliance. Communist Party of India (Marxist) later left the alliance when M. K. Stalin stirred up a controversy by commenting on the alliance partners support for the Tamilaga Vettri Kazhagam led Tamil Nadu Government, saying it was after its (Dravida Munnetra Kazhagam) approval, CPI(M) state secretary P Shanmugam denied it saying it was an independent decision and left the alliance .Communist Party of India and as well as Marumalarchi Dravida Munnetra Kazhagam too withdrew there support and left the alliance.
