West Bengal Chief Minister Mamata Banerjee on Thursday challenged the BJP to prove its allegation that her party, the Trinamool Congress, has misappropriated funds sent by the Centre to the state, or the Narendra Modi government should resign.

Addressing a programme of NGOs and civil society organisations in Kolkata, the TMC supremo claimed that the language used by BJP leader Amit Shah, who is currently on a visit to the state, smacks of arrogance and does not behove a Union home minister.

"The BJP frequently says that TMC is corrupt, the TMC siphoned off money. It is not Modi's money. It is sent by one government to another. Then you should not collect taxes from the state and there will be no need to give it back. If you cannot prove the allegation, you will have to resign," Banerjee said.
