Shah is scheduled to attend a function involving Kanchi seer Jayendra Saraswathi here and is also likely to meet senior office-bearers of the state unit, a party leader said.
"Since the state is going to polls, he will review the political situation but as of now there is no word on him meeting DMDK founder Vijayakant," the senior leader told PTI responding to a possible Shah-Vijayakanth meeting.
According to official sources, Shah is expected to arrive in the evening on Wednesday and proceed to the venue.
BJP's alliance prospects with DMDK, which was part of the NDA for the 2014 Lok Sabha polls, are in a limbo with the actor-politician not only giving confusing signals on a tie-up but also announcing the party's decision to go solo in the May 16 Assembly polls.

Although BJP's Tamil Nadu in-charge and Union Minister Prakash Javadekar had called on Vijayakanth earlier, DMDK had described the meeting as a 'courtesy call.'
Shah, credited with scripting the party's success in the 2014 Lok Sabha polls and some of the subsequent state Assembly elections such as Haryana and Maharashtra, faces an uphill task in ensuring a good show in Tamil Nadu as the voters have traditionally favoured the two Dravidian parties, DMK and AIADMK since 1967.

Sounderrajan said Shah was visiting the city for a "private function" which was "neither political nor party-related."
BJP was trying to revive the front that faced the 2014 Lok Sabha polls but alliance parties are putting forward "some conditions," she said in an apparent reference to DMDK and PMK insisting that their leaders will be the Chief Ministerial candidates.
"But as far as BJP is concerned, people's welfare is our only motive. There is no compulsion for us to form an alliance by making compromises," she told reporters.
