GRAP Stage III Stays In Force Across Delhi-NCR

Stage III of the Graded Response Action Plan remained in force across Delhi-NCR as authorities responded to deteriorating air quality. The pollution also renewed debate over how the Centre and the Delhi government prepare for the seasonal decline in air quality.

Speaking to ANI on Sunday, Rashtriya Janata Dal MP Manoj Jha questioned what both governments had done throughout the year to prepare for winter pollution. He called for scrutiny of the Centre’s role alongside the Delhi government’s and argued that governments should develop and implement a year-round action plan. Separately, Delhi Minister Kapil Mishra alleged in a post on X that Aam Aadmi Party convenor Arvind Kejriwal’s residence was the centre of a campaign to target Diwali and Sanatan Dharma through the pollution debate.
