Meerut

Lewis Blondrage, 25, of Aliwal Barracks, crashed into a telegraph pole in Meerut Road, Tidworth, on 19 November.

Aditi Garg, who works in Meerut town - about 100km from Delhi - used to cherish the quiet moments on her balcony each morning.

Since mid-October, pollution levels in Meerut have remained at levels classified as "poor" or "severe", making it difficult to breathe.

It is a tightly controlled operation: BJP volunteers in Meerut say that each day, the party's headquarters in Delhi sends political messages and hashtags - these range from praising Prime Minister Narendra Modi and the BJP to criticising the opposition - that need to trend to the state-level headquarters.

From there, the messages reach 180 Meerut constituency volunteers, including Ankur.
