CALCUTTA, Nov 2: Announcing that her ``ultimatum to the Union Government on the issue of abnormal rise in the prices of essential commodities stayed'', the Trinamool Congress leader Mamata Banerjee said that her party would ``take a final decision on the issue of staying in the allies coordination committee tomorrow.''Addressing a morning-to-evening dharna at the Esplande against price rise here this evening, she said: ``A high-level Trinamool Congress team, which would take the party's demand on the issue of price rise to the BJP-led coalition at the Centre, will leave for Delhi tomorrow.''Terming the Union Government's response to the issue as late, Mamata Banerjee said she expects a positive outcome of the steps taken by the Prime Minister on the issue since her party had threatened to quit the Coordination Committee of the BJP and its allies on the issue of price.Saying that her party would however take a final decision tomorrow she said ``both the Union and the State Government could haveavoided this present crisis if they paid heed to my warning five months back.''The Trinamool leader ridiculed the West Bengal Government for its decision to import onion so late and deciding to sell it to the people at Rs 20 to 22 a kilogram through the PDS.Saying that ``the State Government waited for the price to go up so that they could tell the people that the Union Government is responsible for this mess-up,'' she said: ``the real story is that the CPI(M) leaders have joined hands with the unscrupulous profiteers, hoarders and blackmarketeers to plunder the people in the state.''Announcing a series of agitational programmes which the party will undertake to protest the price rise in the State, the Trinamool Congress chairman, flanked by her party leaders, has asked the CPI(M)-led Left Front to take the issue of price rise and law and order situation very seriously or must be ready to face the consequences. A ten-member Trinamool Congress team will submit memorandum to West Bengal Governortomorrow.
