Chief minister Mamata Banerjee is likely to arrive in Goa by October-end as part of her party’s political programme, with many politicians expected to join Trinamool Congress in the coastal state. This will be Banerjee’s first visit outside Bengal after winning a third term as CM. She is being projected as the alternative to PM Narendra Modi following Trinamool’s impressive win over BJP in the assembly polls. Ahead of Goa assembly polls scheduled next year, Trinamool is also gearing up to increase its strength after former Goa CM and ex-Congress leader Luizinho Faleiro recently joined Trinamool in Kolkata along with several other leaders. Banerjee is likely to stay in Mumbai the preceding night. Sources said that she might meet NCP leader Sharad Pawar.
