Miss Mamata Banerjee, Trinamul Congress chief today alleged that UPA has increased the price of petroleum products many times more than the NDA had, and dismissed the CPI-M's charge that she was silent when the NDA government took the harsh measure. She recalled she had tendered her resignation in protest in 2001 when the NDA government tried to raise the price of cooking gas by Rs 20. "This forced the NDA government to roll back and the increased price was Rs 10.' She said under the UPA regime, the total hike in diesel is 33 per cent and an all-time high hike in cooking gas. "We are demanding that the state government should abolish the cess and sales tax on petroleum products. Due to sales tax the price of petrol and diesel is costlier in the city,' she added. n SNS
