The fares of the Delhi Metro were increased for the second time in a year on October 10.The Congress leader also advised both parties to stop doing politics on the issue which is directly related to the masses."The AAP and the BJP must stop politics on the issues of common man," he said.Delhi Congress workers across the city also collected signatures of Metro commuters against the fare hike.
