The VCK, a long-time ally of the Left parties, is expected to formally announce its support to the Vijay-led TVK on Saturday by following the stand of the communist parties.

The Viduthalai Chiruthaigal Katchi chief Thol Thirumavalavan has already announced that his party's decision would align with the decision of the Left parties that have already extended their support to the Tamilaga Vettri Kazhagam in government formation.
