On the political front, while Kejriwal, who met the TNC supremo for about half an hour, did not reveal the details of the meeting to the media, the BJP rebels expressed their support to Banerjee's endeavours.
Here are the top 10 developments around Mamata Banerjee's efforts to forge a political alliance including the Congress and AAP against the BJP for the Lok Sabha elections 2019:
1) Mamata Banerjee hopes for a Congress victory in Karnataka election 2018:
Having met Sonia Gandhi, Mamata Banerjee said that she hoped for the Congress to win in the Karnataka Assembly elections 2018. "We want a strong political party in any region to take on the BJP one-on-one, so that it is ousted," she said.
2) Mamata Banerjee says Congress needed for a one-on-one fight with BJP:
Mamata Banerjee on Wednesday made it clear that the Congress cannot be left out from an anti-BJP alliance
in the Lok Sabha polls 2019 in which parties that are dominant in a state will take the lead in putting up a one-on-one fight against the BJP. Banerjee, who had been camping in the national
capital for the past two days, drove to the 10 Janpath residence of UPA Chairperson Sonia Gandhi and inquired about her health. The two leaders discussed the political situation in the country.
"I told her that in 2019 elections there should be one-to-one (contest) from everywhere. In all states those parties which have stronghold in their own area they should fight from there," said the TMC supremo, adding, "We want Congress to be with us. Congress should also help in this one-to-one fight. We have spoken to other parties. All states regional parties, in a kind of conclave, should work together."
4) Mamata pitches for Lalu and Congress in Bihar, Akhilesh and Mayawati in UP: Mamata Banerjee has envisioned a federal front
against the BJP across the nation. The TMC supremo said: "...In Bihar, (RJD chief) Laluji (Prasad) and Congress will fight together. In Uttar Pradesh, Akhilesh and Mayawatiji should do it."
Banerjee said that the BJP should be voted out of power in the country and that it would be defeated if Opposition parties come together. "BJP will be removed only if there is one-to-one (contest). I am 100 per cent sure. We want that whichever party is stong in a state, they should fight one-is-to-one to defeat the BJP," added the TMC chief.
5) Mamata Banerjee meets Arvind Kejriwal:
In her efforts to forge a broad coalition of political forces for a one-to-one fight with the BJP in the Lok Sabha polls 2019, Mamata Banerjee on Wednesday met Delhi Chief Minister Arvind Kejriwal. Kejriwal, who met Banerjee for about half-an-hour, did not speak to the media about the meeting.
6) Shatrughan Sinha and Yashwant Sinha say they met Banerjee 'to save the country': Mamata Banerjee on Wednesday got the backing of BJP rebels
Shatrughan Sinha, Yashwant Sinha, and Arun Shourie for her efforts to forge a broad coalition of forces against the BJP. The BJP rebels expressed their support for her endeavours.
Former Union minister Yashwant Sinha met Banerjee along with BJP MP Shatrughan Sinha. They said that they came to meet the TMC supremo because there was a need to save the country. "We worked together for a long time in the (Atal Bihari) Vajpayee government and you are all familiar with her personality," he said. "The role she has played in this direction is admirable. We came to thank her and she should continue discharging the role strongly in the future. She has our full support and cooperation," Yashwant Sinha said.
Shatrughan Sinha, for his part, said that Banerjee was a mass leader who was connected to the grassroots. "We are with her in her struggle for the country. Nation is bigger than the party. All this work is not anti-party but pro-nation. We have come to give her support for the sake of the country," he said.
7) Shourie hails Mamata, says Modi is 'very tired': Shourie hailed Banerjee's push for a one-on-one contest
against the BJP across states in the 2019 elections. "If this one-to-one formula is adopted, the Opposition parties start with 69 per cent of the votes. Because even at the height of his popularity, Modi got only 31 per cent of the votes," he said.
Supporting the TMC supremo, Shourie said that coordination in each state should be left to the dominant leader's wisdom. "He should distribute tickets in such a way that everybody can come together in that particular region," Shourie said.
He also hoped that the principal Opposition party, the Congress, "will see the good sense for everybody to be together".
"Because if this momentum (of BJP's victories) is not broken, there will be no Congress and nobody even among them personally in the second round," Shourie said.
Targeting the NDA government, Shourie said that Prime Minister Narendra Modi had become "very tired now" and had lost his grip on the government. "It seems he is strong, but actually he is busy only with ceremonial stuff. And the government is paralysed," said Shourie, adding, "He is, as Mr Advani said, a very good event manager but he, it is turning out, is only an event manager. He is announcing schemes but not seeing what is happening to schemes. And the people are now seeing that his pronouncements and the results are very different."
8) Mamata opposes Modi government's Air India stake sale:
Mamata Banerjee also opposed Modi government's move to disinvest its stake in Air India. Further, TMC leader Derek O'Brien questioned the decision, saying that a parliamentary panel was still examining the issue.
Hours after the government released the preliminary information memorandum on the strategic disinvestment of the national
carrier, Banerjee took to Twitter to express her objections. "I'm sorry to read in the media about the government inviting expression of interest for selling Air India, the jewel of our nation. We strongly oppose this and want this order to be withdrawn immediately," said the TMC chief. "This government must not be allowed to sell our country," she added.

O'Brien also slammed the Centre's move. "The proposed disinvestment of Air India is being examined by the panel. Stakeholders are being called. Views heard. Report still some time away. How come these moves from government?," he tweeted.

9) BJP says Mamata Banerjee akin to Nero:
The BJP hasn't remained silent through all of this, with the ruling party hitting out at the TMC supremo over incidents of violence during Ram Navami processions in West Bengal. The BJP said that while Banerjee's state was "burning", she was "doing politics"
in the national capital.
BJP leader Prakash Javadekar told reporters that Ram Navami processions were attacked by TMC "thugs" in the state. "Bengal is burning and Mamata is doing politics
in Delhi. It is like Nero fiddled while Rome was burning," he said, while displaying pictures of the alleged violence that took place during the processions.
Javadekar alleged that people associated with the TMC were not only targeting innocent devotees of Ram, but that they also attacked police personnel.
The government also took potshots at Congress President Rahul Gandhi, saying that Parliament proceedings had slowed down since he became the chief of the Opposition party.
10) Mamata Banerjee meets NCP, Shiv Sena, DMK and TRS leaders:
Arriving in Delhi on Monday, Banerjee had met Nationalist Congress Party (NCP) chief Sharad Pawar and MPs of BJP's ally Shiv Sena on Tuesday. She had also met Telangana Rashtra Samithi (TRS) chief K Chandrasekhar Rao's daughter K Kavitha and Lalu Prasad's daughter Misa Bharti besides MPs from Biju Janata Dal, Samajwadi Party, Rashtriya Janata Dal (RJD), and the Dravida Munnetra Kazhagam (DMK).
