Leaders of Bharatiya Janata Party (BJP) plan to stage a dharna at Punnami Ghat in the city on March 12, opposing the Government's move to privatise Bhavani Island. In a meeting held here on Thursday, party general secretary D. Umamaheswara Raju said the Congress party leaders have failed to take up Polavaram and Pulichintala projects. The party will launch ‘porubata' in all divisions from April 1 to 6, said Mr. Raju.
