After the BJP victory in Gujarat assembly elections, Yogi Adityanath, one of the party's top drawer campaigners, set the tone for the assembly polls in Karnataka that will be held early next year. The saffron-robed chief minister of Uttar Pradesh flagged off the BJP's Parivartana Yatra in North Karnataka's Hubbali on Thursday with a scathing attack on the Congress government and pitched Lord Hanuman against Tipu Sultan. The birth anniversary celebrations of the 18th Century ruler had triggered a huge controversy and protests in the state and resulted in the deaths of two persons two year ago.
