The rally will help catapult Banerjee to the centrestage of national politics and also show her capacity to unite all opposition parties to take on the BJP in the coming Lok Sabha elections, according to another TMC leader.
Arun Shourie, a bitter critic of the Modi government, would meet Banerjee later in Kolkata as he would not be present in Delhi during TMC chief's visit, O'Brien said.
The West Bengal chief minister, who would be visiting the Central Hall of Parliament, is expected to personally invite opposition party leaders for her rally of "federal forces" in Kolkata on January 19. "In 2019, it will be collective leadership", she said after her meeting with the Gandhis at 10 Janpath.More news: Judge blocks release of 3-D printed gun blueprints
The Congress later chose to call a full CWC meeting to evolve a proper response on the draft NRC.
On the Congress' indication of its willingness to accept her candidature as opposition's PM face, she said, "I am not for any chair, our aim is to defeat the BJP". "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 40 lakh people who have been left out of the NRC are from Bihar, UP, Jharkhand, West Bengal and other states too. "Where they will go now?"
The West Bengal chief minister, who has strongly criticised National Register of Citizens (NRC) draft for Assam, has also sought an appointment with the Union Home Minister Rajnath Singh to discuss the issue. "I am interested in seeing that all parties should work together". So we want that everybody should be united.
The BJP president is likely to "expose" how Ms Banerjee is trying to play appeasement politics over an issue, which would weed out illegal migrants from Assam, who are using resources meant for Indians and could also pose a security threat to the country. "I met him and inquired him about his health", she told reporters. "It is a tradition, a courtesy", she said when asked about the meetings.
Congress leaders Ghulam Nabi Azad and Ahmed Patel were the first to meet her at the TMC party office followed by Samajwadi Party leader Ram Gopal Yadav and Jaya Bachchan, Rashtriya Janata Dal's Misa Bharati, Tiruchi Siva of the DMK, Kerala Congress MP Jose K. Mani and leaders from TDP and YSR Congress.
