Delhi L-G VK Saxena has written a 15-page letter to former Chief Minister Arvind Kejriwal, highlighting the blunders during AAP's 11 year rule for air pollution in Delhi. "Delhi's dilapidated roads, dilapidated streets, lanes, and neighbourhoods filled with sewage, silt-filled drains, three mountains of garbage, and polluted air have become a clear testimony...of your failures," L-G wrote.
