Shiv Sena president Uddhav Thackeray on Thursday met West Bengal Chief Minister Mamata Banerjee here, fuelling speculations in political circles.The Sena chief, accompanied by son Aaditya Thackeray, paid a visit to Ms. Banerjee in the afternoon at a south Mumbai hotel where she is staying.Both Shiv Sena and Ms. Banerjee’s Trinamool Congress (TMC) have been at loggerheads with the BJP and the Narendra Modi government on a host of issues, including demonetisation.Ms. Banerjee, who is in the city since Tuesday and expected to return to Kolkata on Friday, met top industrialists and bankers here on Wednesday as part of a roadshow. This comes ahead of the fourth edition of the Bengal Global Business Summit, to be held in Kolkata in January. The Shiv Sena had last year teamed up with the TMC in a bid to take on the BJP over the issue of demonetisation.Mr. Uddhav had told mediapersons in November last year that if there was nothing wrong in Prime Minister Modi meeting (NCP chief) Sharad Pawar, then there was nothing wrong if the Sena held talks with Ms. Banerjee on a crucial issue.
