And this is what WB CM Mamata Mukherjee said at the NDC. Her speech was read out by state finance minister Amit Mitra:

Banerjee today accused it of an "unholy nexus" with the erstwhile Left Front government of West Bengal, leaving the state in a "disastrous" financial situation with a debt burden of Rs 2 lakh crore, and warned that patience was running out.

"We have waited for a year and a half but the patience of our people is running out. I am hoping that my presentation today ... will touch a chord in the heart of the government of India to move forward on the debt impasse," Banerjee warned in her speech at the National Development Council meeting in Delhi.

"I must ask as to why the central government allowed the state of West Bengal to fall into a debt trap by becoming a party to the years of profligacy of the Left Front government? In retrospect, this unholy nexus has left our government in a disastrous financial condition," she said in her speech.

It was "unfortunate that the UPA-I and UPA-II governments permitted the Left Front government to rampantly borrow and build up the debt burden," Banerjee said.
