The LPG marketing companies have again increased the price of liquefied petroleum gas (LPG) by Re 1 to Rs 52 per kilogram in Karachi, Rs 54 in Punjab and Rs 56 in NWFP. Chairman of LPG Distributors Association Hadi Khan said here Tuesday that the retail price of 11.8 cylinder is up by Rs 10 to Rs 550 in Sindh while it is Rs 580 in Punjab and Rs 605 in NWFP. He alleged that LPG marketing companies have been increasing their prices without any reason. Hadi has also criticised the authorities for not monitoring the frequent rise in LPG prices and said that government's silence was encouraging marketing companies manoeuvre prices at their will. He alleged that producers have raised LPG prices by Rs 80 to 90 per 11.8 cylinder in the last 15 days. Copyright Associated Press of Pakistan, 2008
