The centre is spreading lies, Delhi Chief Minister Arvind Kejriwal told NDTV today while defending his government against allegations it wasted Rs. 1,500 crore on ads instead of helping farmers eliminate the need for stubble burning that has contributed to the city's air pollution crisis. "I heard Prakash Javadekarji (Union Environment Minister) said we spent Rs. 1,500 crore on ads... in this financial year Delhi government has spent only Rs. 40 crore... on awareness about dengue so that not one person has died this year. The centre lies so much we cannot believe anything they say," Mr Kejriwal asserted.
