BJP state president K Annamalai had earlier said the roadshow will be covering segments of both South Chennai and Central Chennai. Tamilisai Soundararjan is BJP's South Chennai candidate while Vinoj P Selvam is taking on DMK heavyweight Dayanidhi Maran from Central Chennai.

Traffic diversions have been announced by the police in the wake of the PM's event while security has been beefed up in the area.

The BJP, which is heading a bloc that includes Pattali Makkal Katchi and Tamil Maanila Congress-Moopanar, is making all out efforts to put up a better electoral show this time, under the leadership of an aggressive and assertive Annamalai, who is contesting the polls from Coimbatore.

The party has no representation from Tamil Nadu in the outgoing House.
