West Bengal Chief Minister Mamata Banerjee on Sunday accused Prime Minister Narendra Modi of destabilising the country's economy with the demonetisation move."Modiji, you have finished India's economy and growth," Banerjee tweeted. She also said that women would give him a "befitting reply" for scrapping the Rs 500 and Rs 1,000 notes on November 8."The women of our country will give you a befitting reply."The Trinamool Congress supremo also accused the Prime Minister of misusing the government machinery for the sake of own publicity at the time of a national crisis."'Maan Ki Baat' has become 'Modi Ki Baat'. Misusing government machinery. Instead of finding solutions to the suffering and pain of millions, he is doing personal vendetta, personal publicity and business," she said.Earlier on Sunday, Modi made a strong push towards cashless economy and said demonetisation of high value currency notes was a step forward to rid the country of unaccounted hidden wealth and corruption.Banerjee strongly rebuffed his suggestions for using online apps for money transaction."We don't trust you or your mismatched wrong technology which you are advertising for," Banerjee added.
