New Delhi: Senior AAP leader Sanjay Singh on Tuesday criticised Prime Minister Narendra Modi's announcement of the "GST Bachat Utsav", alleging that the new tax structure continues to put a heavier burden on common people while benefiting the rich. Addressing a press conference, Singh said, "PM Modi has announced the Bachat Utsav following the implementation of the new GST rates. "This is not a Bachat Utsav, it is a Chapat Utsav," Singh remarked. "We never knew that after the Bihar assembly polls, the GST rates would be raised again," he added. On Sunday, the prime minister had described the new GST structure, rolled out from the first day of Navratri, as a "Bachat Utsav" for shoppers, saying it would lower prices of a wide range of goods.
