She is against calling "bandhs" (work stoppage) although actively supported them when she was in opposition. Her tenure was also heavily marred by the Saradha Scam - a financial embezzlement which led to the imprisonment of Madan Mitra - a former minister in her cabinet, Kunal Ghosh-a party MP, and rigorous grilling of several party men holding important posts.  2016 West Bengal Legislative Assembly election was held for 294 seats (out of 295 seats) of the Vidhan Sabha in the state of West Bengal in India. All India Trinamool Congress won the elections with a landslide two-third majority under Mamata Banerjee winning 211 seats out of total 293, who has been elected as Chief Minister West Bengal for the second term. All India Trinamool Congress won with an enhanced majority contesting alone and became the first ruling party to win without an ally since 1962 in West Bengal. The Saradha Group financial scandal and the Rose Valley financial scandal came to light during her tenure and some of her cabinet ministers were accused of money laundering and have been incarcerated. One of her paintings was also sold to Sudipto Sen (central figure in the Saradha scam) for ₹1.8crore, while 20 more of her pictures were seized from other Saradha Group shareholders. She has been criticised by opposition parties for not taking adequate steps against her own ministers who tried to cover-up their deeds. The Rose Valley financial scandal was a major financial scam and alleged political scandal in India caused by the collapse of a Ponzi scheme run by Rose Valley Group where multiple MPs from Banerjee's party was accused of money laundering. The Narada sting operation was carried out by Mathew Samuel in 2011 for the Indian newsmagazine "Tehelka" and published on Naradanews.com just before the 2016 West Bengal Assembly elections. The sting targeted high-ranking officials and politicians of Banerjee's political party All India Trinamool Congress (AITC). During her tenure she challenged the federal system of India when she ordered the arrest of CBI officials, who arrived in Kolkata to investigate the Saradha Group financial scandal. Mamata Banerjee has been criticised for starting controversial stipends to imams (Iman Bhatta). which was ruled unconstitutional by Calcutta High Court and ordered the West Bengal government to stop payment of a monthly stipend to thousands of imams and muezzins in the state. In October 2016, the West Bengal government banned the Durga Puja festival immersion after 4:00 pm. Durga Puja was to take place on 12 October and Muharram on 13 October.
