Dedicating the world's longest LPG pipeline from Kandla in Gujarat to Loni in Uttar Pradesh to the nation, Prime Minister Atal Bihari Vajpayee said that the demand-supply scenario on LPG has taken a u-turn. Earlier there was huge demand for LPG but the supply was restricted, but now the supply has superseeded the demand. The recent development would further boost up the supply chain which would lead to immense economic development in Delhi.
