New Delhi: Around one crore families have till date given up cooking gas subsidy, Prime Minister Narendra Modi said on Sunday. "I want to congratulate those one crore families who gave up their subsidies. It is not a small thing," he said in his monthly 'Mann ki Baat' broadcast on All India Radio. The prime minister recalled how he had urged people to give up the subsidy on liquefied petroleum gas (LPG). Moreover, over 80 percent of small-income families of pensioners, farmers, school teachers and shopkeepers, forming the overwhelming bulk of those who surrendered the subsidy, chose to do so by visiting LPG distributors. "They did not avail of the option of surrender available on mobile apps, online or by simply giving a missed call," he said.
