BJP is making hectic preparations ahead of tomorrow's nomination by Narendra Modi, who will undertake a "grand road show" before filing his papers for the mega battle in this holy city where he is challenged by AAP leader Arvind Kejriwal and others. Modi's campaign managers said lakhs of people are expected to participate in the two-km-long road show from Nadesar to Kacheri locality in the heart of the city during which a number of leading local organisations will greet him.
