Mamata Banerjee on Monday said while efforts were underway to put together a mohajot (grand alliance) against the BJP nationally, the CPM and the Congress continued trying to work with the BJP in Bengal in what she called a mohaghnot (grand plot).

“We are trying to form a mohajot against the BJP at the Centre, but the CPM and the Congress keep trying to work with the BJP, in a mahaghnot, in Bengal. I will destroy this sinister tie-up here,” the Trinamul Congress chairperson said in her address for the panchayat poll campaign in Cooch Behar district.

The Bengal chief minister had attended a meeting in Patna on Friday, alongside the top leadership of the Congress and the CPM, in a step towards the formation of a grand alliance against the BJP.

Bengal Congress chief Adhir Ranjan Chowdhury had said on Sunday that the Patna-esque developments wouldn't dilute his party’s fight against Mamata.

Responding to her accusation, Chowdhury on Monday said: “The very credibility of Trinamul, in the fight against the BJP, has never been without a major question mark.”

In her address, Mamata brought up Prime Minister Narendra Modi's recent US trip. “They have gone to the US, wasting millions of dollars in (Indian) taxpayers’ money to please them. Modibabu neta hobey (Master Modi will become a leader),” she said.

“The Prime Minister is busy roaming around in the US… and the BJP thinks they can bulldoze anything, or shoot anyone they wish to eliminate,” she said.

Mamata had on Thursday refused to blame Modi for his recent US trip amid turmoil in Manipur, saying such prior commitments often couldn't be rescheduled.
