Samajwadi Party chief Akhilesh Yadav on Sunday called the Delhi pollution issue an "annual" topic and said its effects had started reaching Uttar Pradesh. The BJP and AAP traded barbs over pollution levels in Delhi as the national capital's air quality once again slipped into the 'very poor' category after a two-day gap. Yadav said in a post on X, "The havoc of pollution in Delhi has become an 'annual' topic.

This is called 'chiraag taley andheraa (darkness below the lamp)' or 'dhundhalkaa (dusk)'." "The BJP government, which claims to be making the country proud across the world, is not able to save the country's image from getting blurred by the smog in the capital itself.
