NEW DELHI: Trinamool Congress chief Mamata Banerjee today said she was not vying to be the prime minister and that the first priority was to defeat the BJP which is "scared and nervous" to face the 2019 polls because of opposition unity.

"The opposition is united... In 2019 BJP will be finished," Banerjee, who invited the leaders of the opposition parties as well as Sena chief Uddhav Thackeray to her January 19 rally in Kolkata, told reporters.

Banerjee has been at the forefront of efforts to rally opposition parties for an anti-BJP front. The West Bengal chief minister spent the second day of her Delhi visit meeting leaders of various parties including Sonia Gandhi and Congress president Rahul Gandhi .

Besides leaders of the Congress, TDP, YSR (Congress), DMK, RJD, SP, AAP and JD(S), she also met BJP veteran L K Advani, Shiv Sena leader Sanjay Raut and dissident BJP leaders.

Her January-19 rally is being seen as an attempt to catapult Banerjee to the centre stage of the anti-BJP front.

"We are all for all. We will take a decision on collective leadership. If all opposition political parties can join hands and work together in Parliament, then why not fight unitedly outside," Banerjee told reporters after her meeting with the Gandhis at 10, Janpath, the residence of Sonia Gandhi.

When asked if she would be vying for the post of Prime Minister, she said that her primary aim is to prevent the BJP from coming to power in 2019.

"I am not for any chair, our aim is to defeat the BJP," she said.

Banerjee said she met both Sonia Gandhi and Rahul Gandhi and discussed the NRC issue as 40 lakh people have not been included in it and genuine voters had been kept out.

"We discussed the political situation. We discussed how the opposition can together take on the BJP because it knows that it will not come back to power," she said.

The TMC chief also looked annoyed with BJP president's attack on her over the NRC issue yesterday. "I am not his servant. Why should I reply to his comments," she retorted. "Gali ka jawaab hum gaali se nahin denge. Yeh hamari parampara hai. (We will not reply to an abuse with an abuse, that is our tradition)," she added.

"The BJP is scared and nervous politically due to the unity of opposition parties. The BJP knows what will happen to them in 2019 as they will not come back to power. That is why they are trying to create such an atmosphere and doing all this," she said.

On her meeting with leaders of various political parties, she said, "We know every political leader. I am happy to meet all of them."

Attacking the Centre on Assam's National Register of Citizens final draft, she said, "People whose names have been kept out are from Bihar, UP, Tamil Nadu, Gujarat, West Bengal. We want them to live peacefully. Some of them are living for 100 years for five generations in Assam. How can you do this to them?"

Later in the day, the TMC chief also met AAP leader Arvind Kejriwal in the capital. The two leaders, however, did not speak to the media after the meeting that lasted for around 35 minutes.

Banerjee had stirred a controversy yesterday when she warned of a civil war and bloodbath in the country in case 40 lakh people of Assam are left out of the NRC.

"I do not know what the BJP wants -- a civil war or a bloodbath. But we do not want it," she said today.

On a tie-up with the Congress in West Bengal, she said every party will take its own decision.

"I cannot interfere in the Congress's decision. We believe that the strongest in a state should take on the BJP," she said.

The TMC office in Parliament was abuzz with meetings after Banerjee arrived there today. The TMC chief met Congress leaders Gulam Nabi Azad, and Ahmed Patel, Samajwadi Party leaders Ram Gopal Yadav and Jaya Bachchan, DMK leader Tiruchi Siva, YSR Congress leader Vijaysai Reddy, RJD leaders Misa Bharti, Jayprakash Narayan Yadav among others.

Banerjee met JD(S) leader Deve Gowda at Karnataka Bhavan and invited him to the rally.

She also met Advani at his chamber in Parliament House. “I went to meet him and enquired about his health," she told reporters.

Suspended BJP Member of Parliament Kirti Azad hailed her as a great leader and said that her efforts to consolidate all opposition parties are "commendable".

The TMC chief later went to the Central Hall of the Parliament to meet other opposition leaders and invited them to the rally.

Banerjee also appealed to all the opposition parties to send a joint delegation to the Election Commission against EVM tampering and to press for holding polls on ballots. "All opposition parties should go to EC on this matter," Banerjee told the leaders.

Interestingly, Banerjee extended an invitation for the rally to the Shiv Sena chief through Raut who said the party would take a decision on it. Though a constituent of the NDA, the Sena has been openly critical of the Modi government.

She also appealed to the leaders to send an all-opposition-party delegation to Assam stating that though TMC delegation would be visiting the state on Thursday, other parties should also exert pressure on the government.
