Delhi Chief Minister Arvind Kejriwal has guaranteed free public travel for students and basic facilities for unauthorised colonies in the city along with continuing the ongoing free subsidy on water and electricity in his “guarantee card” ahead of the February 8 Assembly polls. The ‘Kejriwal ka Guarantee Card’ to be released on Sunday by the Chief Minister has 10 “guarantees”, including a promise to reduce air pollution in Delhi by three times. “We will plant more than two crore trees to make Delhi green,” the card reads.
