A spokesman for the B.J.P., Tom Vadakkan, stated that the evictions had nothing to do with the G20, and that the federal government was serving to the displaced get enough housing.

Residents of a lately bulldozed New Delhi slum disagreed.

Squatting on the particles of their belongings, some stated they hoped they may return to their authentic houses sometime. Karan, a day laborer who goes by one identify, dug out a photograph of himself subsequent to a cutout of Mr. Modi, with a multistory housing block within the background.

“We were herded in a bus by some B.J.P. workers earlier this year, just before the local municipality elections, and told we will get these homes after the elections,” he stated, teary-eyed. “We were then asked to pose with Mr. Modi’s cutout.
