Calcutta, Sept. 3 :    Calcutta, Sept. 3:  Mamata Banerjee today threatened to resign from the Vajpayee Cabinet for not being able to bring 'peace' to Bengal villages. The Trinamul Congress leader and railway minister made the threat at the party's policy-making body which met until late tonight after the maha mahamichhil (grand procession). Sudip Bandopadhyay, Trinamul MP, said Mamata decided not to force the issue after she received at least six phone calls from BJP leaders, including home minister L.K. Advani, when the meeting was going on at Nizam Palace. 'Mamata said she wanted to quit as she had failed to mount pressure on the BJP-led government to declare five Bengal districts as disturbed, let alone impose President's rule,' he said. He said a team of Trinamul leaders would call on the Governor tomorrow and submit a memorandum demanding that Midnapore, Birbhum, Hooghly, Bankura and Burdwan be declared 'disturbed'. Mamata also announced that she will undertake a three-day visit to trouble-torn areas in Midnapore, Bankura and Hooghly tomorrow. After that, she will convene another meeting of the policy-making body. Sources said Mamata told today's meeting that when people belonging to minority communities, scheduled castes and tribes and women and children were being attacked, the Centre should intervene. 'We will have to convince the Vajpayee government that the situation in the state warrants immediate central intervention. Otherwise, what is the use of my being a Union minister from Bengal?' Mamata wondered. Even if today's threat was not for real, the BJP-led government can expect the Trinamul leader to keep up the pressure for action on Bengal till the elections. By being seen as pressuring the Centre to act, she keeps the Left Front on tenterhooks, especially if Jyoti Basu steps down. With Basu out of the way, it becomes that much more easy for Delhi to act. As of now, high-level government sources ruled out interfering in Bengal. Trinamul leader Pankaj Banerjee said Mamata will continue 'the threat until the Centre meets our demand'. If having to live with an increasingly demanding Mamata was one piece of bad news for Delhi, the other was the hint of a group of BJP workers joining Trinamul. After leading a mammoth procession through the city, Mamata declared at a rally that some BJP leaders were about to switch parties. 'Parasbabu has told me he wants to join Trinamul,' she said. The induction of Paras Dutta, former general secretary of the Bengal BJP, is expected to be formalised shortly. Sources close to Dutta said at least 1,200 supporters, including key party functionaries, will follow suit. 'Those who are being sidelined have no option but to join Trinamul,' said another former general secretary Rahul Sinha. BJP state president Asim Ghosh, however, claimed only a few would cross over to Trinamul. 'This will not affect the relations between the parties,' he added. With the chipping away at the BJP block about to begin, the denudation of the Congress camp continued apace. Two MLAs - Motahar Hossain from Birbhum and Phani Bhusan Roy from Malda - joined Trinamul today. Mamata's maha mahamichhil - in protest against the 'reign of terror unleashed by the CPM' - turned out to be a huge show resplendent with colourful tableaux and effigies depicting the 'end of Marxist rule in West Bengal'. The procession snaked its way from the foot of Gandhi's statue on Mayo Road, along Jawaharlal Nehru Road and C.R Avenue towards Shyambazar. At one point of time, when the head of the procession was nearing Shyambazar, the tail was yet to leave the Esplanade area. It took Mamata nearly four hours to reach Shyambazar where she addressed the rally from atop a vehicle as no dais had been built on her instructions in deference to rules which do not allow it. 'In Bengal, the state is sponsoring terrorism. CPM cadre are taking over village after village in rural Bengal with arms supplied by the administration,' Mamata said. 'There is absolute dictatorship going on in Bengal. Our struggle will continue until the CPM is ousted from the state,' she said to thunderous applause. She appealed to people to exercise austerity during the Pujas and contribute to the rehabilitation of thousands who were made homeless in the troubled districts.
