The BJP's key ally, Shiv Sena, has criticised the Modi government over its decision to hike rail fares. Now, Sena chief, Uddhav Thackeray's son, Aaditya, who heads the party's youth wing, tweets: "A minimal hike is understandable, but current hike has put immense strain on the commuters. Inflation n hikes is what NDA sought to control."
