Mamata Banerjee-led Trinamool Congress has reportedly asked its 18 Members of Parliament (MPs) to camp in national capital New Delhi to step up pressure on the UPA government to roll back the recent petrol hike. A television channel quoted Trinamool sources as saying that Banerjee has the resignation letters of the party's central Cabinet ministers with her. The MPs,some of whom are central Cabinet ministers,have sought an appointment with Prime Minister Manmohan Singh on Tuesday to discuss the fuel price issue. The TMC,according to party sources,wants some action before Manmohan Singh leaves for the SAARC Summit in the Maldives later this week. Trinamool Congress Parliamentary Party in Lok Sabha Sudip Bandyopadhyay said: We will return to Kolkata on November 9 and report our discussions with the Prime Minister to Mamata Banerjee. She will take the final call. I have sent a letter to the PMO seeking an appointment on November 8. I am expecting the appointment will be given since the PMO tells me the Prime Minister will go abroad on November 9. Bandyopadhyya added,We'll express our concern to the Prime Minister. There is a huge lack of co-ordination among the constituents in the UPA. No meeting is held with allies before policy decisions are taken. We want to express our sentiments to the Prime Minister. We are a pro-people party. Fuel prices were hiked 11 times in 12 months, he said. Last week,Banerjee threatened to pull out of the UPA alliance over the Rs. 1.82 fuel price hike,even as the Opposition dared her to carry out her threat. Even with a Cabinet minister and five junior ministers at the centre,Banerjee has said her party does not have any say in government decisions. While the Prime Minister''s Office (PMO) is yet to confirm an appointment with the Trinamool lawmakers,Banerjee is hoping for some action before Singh leaves for Male The TC parliamentary party has already authorised her to take the decision in the matter after they decided on November 4 to pull out of the government if there was no rollback.
