Mamata Banerjee on Tuesday said her Brigade meeting on Saturday would be a “mega” rally that would be attended by virtually all regional parties with the common intent of ousting the BJP from the Centre.

“Jyoti Basu had organised a similar meeting in 1977, where some national leaders had participated. But that was not as big as the one to be held on January 19. It will be a mega rally,” Mamata said on Tuesday evening after a meeting with the senior leadership of Trinamul, MPs and police at Nabanna.

The Bengal chief minister named several leaders who she said had already confirmed participation: Sharad Pawar of the NCP, H.D. Deve Gowda and H.D. Kumaraswami of the JDS, N. Chandrababu Naidu of the Telugu Desam Party, Akhilesh Yadav of the Samajwadi party, Farooq Abdullah and Omar Abdullah of the National Conference and Arvind Kejriwal of the Aam Aadmi Party.

Mamata said leader of the Opposition Mallikarjun Kharge would represent the Congress as UPA chairperson Sonia Gandhi was “unwell”.

Asked if the CPM would attend the rally, Mamata said she had invited Kerala chief minister Pinarayi Vijayan but he was yet to respond. “If somebody doesn’t want to come because of his or her political obligations, I respect that.”

BJP MP Shatrughan Sinha will also take part in the rally.
