Prime Minister Narendra Modi inaugurated the much-anticipated Janakpuri West-Krishna Park Extension Metro line in Delhi with a grand rally in Rohini. But the political battle over development in Delhi intensified, with the AAP and BJP sparring over Metro expansions and projects. PM Modi took sharp jabs at the AAP government. He repeated the "AAPDA" attack at the Aam Aadmi Party. Former Chief Minister Arvind Kejriwal hit back saying that AAP worked despite roadblocks put up by the BJP-led Centre.
