[Read: Why is Anna praising Mamata?]
State BJP president Rahul Sinha pointed out in the letter that even Goa chief minister Manohar Parikkar has not taken government car and bungalow.
"She (Mamata Banerjee) is the torch-bearer of the tyrannical CPI(M). The CPI(M) had given birth to hundreds of chit funds in the state, and TMC is carefully nursing them," the letter read.
The BJP wrote about the various 'failure' of the Mamata Banerjee government
The letter also said that in the last 36 years of the chit funds' existence, not a single bill had been passed in the state to curb them, be it the CPI(M) or Trinamool.
"The Sarada chit fund scandal has rocked the state by cheating more than Rs. 10,000 crore from rural people of the state," Sinha said in his letter.
Sinha also reminded Hazare that while chit fund scam-affected states like Assam, Tripura, Bihar and Jharkhand were pressing for a CBI inquiry, the Trinamool Congress government in West Bengal had expressed opposition against it.
The letter also highlighted alleged involvement of district magistrate Kiran Kumar in a scam with local TMC ministers involving the North Bengal Development Board.
When it was exposed by commissioner Jayaraman and legal action opened, he was sent to compulsory waiting and he is waiting till date, Sinha wrote.
The letter referred to the rise in rape cases and the worsening law and order situation under the present dispensation.
The letter also highlighted an allegation of huge monetary transaction on appointments made beyond the merit list.
"Annaji, this is just a few glimpses of your patronized CM. She is giving money to illicit liquor consumers (stopped by High Court ). She is giving money to clubs (for patronizing hooligans), she is spending enormous money for fun and fiestas, which could have been given to poor people or could have been used for development of West Bengal," Sinha alleged in the letter.
