It seemed impossible. Speculation that ignored decades of fierce rivalry.
But the stand-off between Tamil Nadu Governor RV Arlekar and superstar actor Vijay's Tamilaga Vettri Kazhagam - which won 108 seats in last month's election to finish as the single-largest party, though 10 short of majority - has opened the doors for an unprecedented alliance between the Dravida Munnetra Kazhagam and All India Anna Dravida Munnetra Kazhagam.
On Friday afternoon source said the AIADMK had been asked to cut ties with the Bharatiya Janata Party, a 'communal party' - with which it had allied for last month's election - before any discussion. The DMK indicated it could only then extend external support, though with additional conditions, including ministerial berths for smaller allies like the Viduthalai Chiruthaigal Katchi.
The DMK reportedly hopes this will persuade the VCK to deny Vijay its two seats. And that plan seems to be working; separately, sources said the VCK leadership - which seemed to be leaning towards Vijay yesterday - is now back in the DMK's camp and is working to similarly convince the Communist Party of India (Marxist) and the Communist Party of India.
The CPM and CPI were also approached by Vijay, who seemed to be working off a Congress + Left + VCK formula to pick up nine seats to put the TVK inches from the majority mark of 118. But the Left is not seen to be in favour of a DMK-AIDMK alliance, preferring to either stay neutral or, as some within are insisting, move to ally with Vijay and the TVK.
Senior Left leaders will meet this afternoon to decide their next step.
The Congress has committed its five seats, a switch that means it is now fighting the DMK, with whom it won three elections in the past seven years. Manickam Tagore - among a handful who anticipated Vijay's triumph and pushed for a pre-poll deal - this morning accused the DMK of having 'betrayed secularism' by aligning with the 'BJP's B team', i.e., the AIADMK.

Based on numbers published by the Election Commission, a DMK-AIADMK deal will be 120-strong, assuming each party's allies remain on board.
The DMK-AIADMK 'alliance'
It appears the two big Dravidian parties' are driven by similar fears - that the rise of Vijay will keep both out of power for the foreseeable future.
For the DMK this brings back memories of 1977-87 when the AIADMK, led by the iconic MG Ramachandran, kept it from winning any election till after MGR died.

The AIADMK is driven by identical, though more recent, concerns, with sections within pointing to the Stalin-led DMK's control in the past decade, in which the AIADMK lost three straight polls.

Both sides, however, are keenly aware of potentially massive backlash from voters, not only because of the mandate Vijay was given - the TVK picked up 35 per cent of the votes - but also from hardcore supporters from each camp.

Ironically, many have seen the BJP's hand in this coming-together; the theory is that the saffron party is determined - even at the cost of excluding itself - to keep the Congress from even a share of power in Tamil Nadu.
Speculation also linked the BJP to the stand-off between the TVK and Arlekar.

But the party's state unit spokesperson, N Thirupathy, said otherwise, telling reporters, "It is a fractured verdict... TVK doesn't have a majority. If he (Vijay) proves a majority, then the governor will constitutionally accept it. There is no confusion..."
