Mani Shankar Aiyar, a veteran Congress leader, has criticized the party's decision to ally with the TVK in Tamil Nadu, calling it 'dreadful' and 'low political opportunism'. Aiyar made the comments in an article published in The Hindu Tamil on Friday, saying that the move would facilitate the backdoor entry of the 'communal BJP' into the state.

The Congress party had announced its support to actor-politician Vijay's TVK on Wednesday, just days after fighting an election with the DMK. Aiyar said that the decision was a violation of Mahatma Gandhi's maxim of 'Swaraj should be a government based on morality' and that it smacked of opportunism.

Aiyar also questioned the wisdom of abandoning a long-time ally like the DMK, which had stood by the Congress even in difficult times. He argued that the move was not only amoral but also politically flatfooted, and that it would damage the party's reputation in the long run.

The TVK had won a significant number of seats in the recent election, and the Congress party's decision to ally with it has been seen as a strategic move to gain power in the state. However, Aiyar's criticism has sparked controversy within the party, with some leaders questioning the wisdom of the alliance.

The immediate next steps for the Congress party and the TVK alliance are unclear, but it is expected that the two parties will work together to form a government in Tamil Nadu. The DMK, which had been a long-time ally of the Congress, has yet to respond to the development, and it remains to be seen how the party will react to the Congress's decision to ally with the TVK.
