After that there is Bihar and Bengal and we're going to form a government in Bengal too," Mr Shah said, asking crowds to cheer louder because "Mamata must hear."He landed in West Bengal today amid buzz that four ministers in the the government of Ms Banerjee, who is West Bengal chief minister, and one party lawmaker may quit her Trinamool Congress to join the BJP.Ministers Rachpal Singh, Rabi Ranjan Chatterjee, Krishnendu Choudhury and Sadhan Pande of the Trinamool Congress are said to be in talks to join the BJP. The names of some others are also doing the rounds. One, Manjul Krishna Thakur, had joined the BJP last week.Dinesh Trivedi, a Trinamool MP and former Railway minister is also reportedly poised to join the BJP.

The BJP had so far been a small player in the state, but has made it clear that it has it eyes set on changing that. It has been building its base in the state after posting its best performance yet in the national elections last year.
