BJP's national leaders L.K. Advani, party president Rajnath Singh, M. Venkaiah Naidu and Sushma Swaraj are set to visit the state to campaign for their party's candidates in the next 10-12 days.
AAP leader Arvind Kejriwal visited the state for two days March 15-16, before the election was notified March 19 and held road shows across Bangalore and Chikkaballapur, about 70 km from here.
He is expected to visit again at least once to campaign for his party's candidates in other constituencies.
"We are waiting for Kejriwal's office for dates when he will be able to tour others parts of the state though he had already covered Bangalore.
