Prime Minister Narendra Modi said Thursday the BJP is open to alliances and cherished its old friends, in a hint that it was looking to strengthen the NDA in Tamil Nadu ahead the Lok Sabha elections.

In an interaction with party booth-level workers from five districts in Tamil Nadu through video conferencing, he recalled the “successful coalition politics” ushered in by former prime minister late Atal Bihari Vajpayee in the 1990s and said the BJP’s doors were “always open”.
