The ongoing face-off between the BJP and the Aam Aadmi Party over Delhi's mayoral election played out on the capital's streets today. Both parties organised protest marches against each other. While AAP supporters protested outside the BJP headquarters, BJP workers marched to the residence of Chief Minister Arvind Kejriwal. At the Chief Minister's residence, Delhi Police had to use water cannons on the 2,000-odd BJP workers who had gathered there for the protest.
