MUMBAI, OCT 21: After three attempts to topple the Congress-NCP government came unstuck and it just completed one year in office, the ShivSena is ready to eat humble pie: it will now concentrate on being a more ``effective Opposition'' in the ensuing winter session of the legislature.This reality dawned on the party at a two-day brain-storming session chaired by Uddhav Thackeray for party legislators at Walwhan Holiday resort near Lonawala. Other leaders who attended the conclave were Manohar Joshi, Narayan Rane, Madhukar Sarpotdar and Datta Nalawade. They had a direct interaction with the party MLAs on the role of the Opposition in a parliamentary democracy.``We did not discuss the toppling game. But we took serious note of Chief Minister Vilasrao Deshmukh's boast that his government has not given a opportunity to the Opposition parties to take out a single procession. We will present ourselves as a more effective Opposition party and take the government to task for its failure on all fronts,'' a senior Shiv Sena leader said.Wiser from the meeting, the Sena is likely to set up separate groups to chalkout a comprehensive action plan to expose the government's failure on all fronts. ``Compared to our government, their performance is dismal. Whether on the law and order situation or financial condition of the state, it has failed to deliver the goods. We will use the Nagpur session as a platform to expose the government,'' the Sena leader said.Both Rane and Joshi asked the legislators to carefully study the main issues before the state to help the party trap the Deshmukh government. ``We will have to find out that during the one year in office, where the government has committed blunders and then take all possible democratic steps to ensure that the decisions are reversed,'' the Sena leader added.During the Nagpur session, the Sena will take the Chief Minister to task for dereservation of some of the plots in Pune city as well as on the texile mill lands sale in the metropolis. ``Both are important issues. While in Pune, there is apparently misuse of power to oblige a section of politicians, in the textile mill lands case, the government did not take the Opposition into confidence before taking such a major decision. In fact, if permission for disposal of surplus mill land is given, it will have an adverse impact on the textile workers,'' Rane said.
