There had been a great bonding between Trinamool Congress chief and West Bengal chief minister Mamata Banerjee and former chief minister of Andhra Pradesh, Chandra Babu Naidu. Moreover, she had been a role model for CBN. CBN even tried to project her as Prime ministerial candidate for India. Also had he campaigned for her party in Lok Sabha elections. For these reasons, CBN visited Kolkata for nearly a half dozen times.
All this was done by him to develop an anti-BJP coalition. However, he had to face a huge loss by losing both at the National level and assembly level. This made him lose interest in national politics. Still, he maintained good relations with his National friends. Even after BJP won, he condemned the post-poll violence in West Bengal. Right now, some actions of Mamata seemed to have disappointed CBN. Mamata is said to be going to assign Prashanth Kishor to provide his services for next assembly elections.
Everyone almost knows that he was one of the hands behind the victory of YSRCP in assembly elections. As Mamata had signed a contract with Prashant, CBN seems unable to digest this issue. CBN even called him Bihari criminal once. That increased the negative impact on CBN for Prashanth. The impact of the latest relationship of Mamata has yet to be seen on CBN.
