Party sources said Banerjee is in touch with her Arunachal Pradesh MLAs.

“The issue of being a part of the Congress-led government there will be finally decided by the five elected MLAs in Arunacahl Pradesh Assembly,” said Mukul Roy, senior Trinamool leader and Union Minister of State for Shipping.

“It is very difficult for the party to sit with the BJP in the Opposition when we are a partner of the UPA at the national level. But the issue of joining the government will be decided only after the Congress invites us to participate,” said a senior Trinamool leader, adding his party has not received a formal offer from the Congress.

Meanwhile, Banerjee has asked her senior party leaders to visit Jharkhand before finalising nominations. “Once we have a presence in three Assemblies, the Trinamool will be considered as a national party,” said a leader.
