Bengaluru's Pink Line Metro is set for inauguration by Prime Minister Narendra Modi, but the launch has triggered a political battle over funding and credit.

Chief Minister DK Shivakumar says the state also shoulders land acquisition and other expenses. With both sides disputing the numbers, who really paid for Bengaluru's new Metro line?
