"The BJP is not waiting for any one. We are making all preparations but we have not closed our door. It is for Mamata to decide how committed she is to dislodge the Left Front government in the state," party general secretary Narendra Modi told newspersons here.

BJP's commitment to defeat the leftists in the state was evident from its willingness to be part of a `mahajot' proposed by her, he said.

Meanwhile, BJP President Jana Krishnamurthy told Star News in the capital that the party would go on its own in the Assembly elections if Ms Banerjee did not make an open announcement that her party would support BJP-led government at the Centre in the Lok Sabha.

In another development, Congress general secretary in charge of West Bengal Kamal Nath had a meeting with Ms Banerjee in Kolkata on seat adjustments between the two parties. This is the first contact between the two parties after Ms Banerjee resigned as minister at the Centre and pulled her party out of the National Democratic Alliance coalition.

Mr Kamal Nath said his meeting was to establish the fact that Trinamool Congress had dissociated from National Democratic Alliance and Bhartiya Janata Party. "It is very clear and that is what has initiated these talks," he said.
