West Bengal Chief Minister Mamata Banerjee on Monday branded the Goods and Services Tax (GST) a "Great Selfish Tax" and said it was being used to harass people and destroy the nation's economy.
She also termed the demonetisation a disaster and urged Twitter users to change their display pictures to black to protest against the note ban.
"Great Selfish Tax to harass the people. To take away jobs. To hurt businesses. To finish the economy. (The government) totally failed to tackle GST," Banerjee tweeted.
"Note ban is a disaster. On November 8 Black Day, to protest against this scam that destroyed the economy, let us also change our Twitter DP (display picture) to black."

Banerjee changed the display picture of her Twitter account to black on Monday.
The Trinamool Congress chief had earlier instructed her party leaders to observe "Black day" against demonetisation on November 8 to mark its first anniversary.
Similarly, Aam Aadmi Party on Saturday said it will observe November 8, the first anniversary of the demonetisation of high value currency by the government, as "fraud day".
"On this day, we will stage nationwide protests against the wrong policies and the incorrect decision of demonetisation taken by the BJP-led central government," Delhi Rural Development Minister Gopal Rai told media.
Rai also said the party would organise a national conference on November 26 to celebrate the completion of its five years, as decided in the party's National Council Meeting on Thursday.
"Party members from across the country will assemble for this conference and there will be discussion on works undertaken by the party till now.
"We will talk on issues related to farmers who have been deceived by the Centre. Apart from this, there will be dialogue on the demonetisation and GST (Goods and Services Tax)," he said.
"These two decisions by the BJP government at the Centre have ruined the country's economy."
