The onion crisis is four years old but its memory is still fresh in the mind of former Delhi chief minister and MP Madan Lal Khurana. So when he compared it with the CNG crisis, an issue which may lead BJP to another defeat in the coming municipal polls, he stressed on the "complete redressal" of this problem. Khurana announced that the representatives of various auto, taxi and bus associations, will hold a dharna in front of the Supreme Court on August 17.The dharna will be held to appeal to the court to reconsider its order, which would make the transport system in Delhi dependent on a single fuel, Khurana said at a press conference today.
