Kolkata: The fissures within the Trinamool Congress (TMC) are all set to come out in the open as the party’s former second-in-command, Mukul Roy, is set to join a new political outfit.

The advertisement of the new party, named the Nationalistic Trinamool Congress, has been floated in newspapers though it did not name Roy as an office bearer.

Sources however say Roy is the prime mover and ousted Communist Party of India — Marxist (CPI-M) leader Abdul Razzaq Molla is also set to join the outfit.

Roy has been keeping his cards close to his chest. Even though he attended a programme of the new outfit, he did not divulge his next move.

“Life is dynamic and does not stand in one place. I will tell you when I want to say,” Roy told reporters.

However, people close to the developments say he is waiting for the approval from the Election Commission (EC) and only after that will he divulge his next move.

TMC leaders have expressed their unhappiness over the issue and the party said it will take disciplinary action against Roy post the Durga Puja festival.

“If you claim you are still a member of the party you cannot attend a programme organised by party baiters, it violates the basic discipline of the party,” said a TMC leader.

Roy on the other hand appears to be waiting for party chief Mamata Banerjee to take action.

“He [Roy] knows Didi [Banerjee] well enough to anticipate her next move. Till date he had not spoken a single word against the party knowing very well that it will irritate her more. Had he made statements against TMC it would have given much relief to her,” said a insider close to Roy.

TMC leaders anticipate that Roy may actually break the party in rural West Bengal just ahead of the elections in 2016 so that the party becomes structurally weak.

“He knows the organisation structure well enough as he was the architect of the same. He will try to break the party and time it well so that there is little room for recovery. We are taking precautionary measures,” the TMC insider said.

TMC has already promoted Banerjee’s nephew Abhishek to take over the Roy and though he has succeeded in various municipal polls assembly elections is a bigger battle and Roy is a worthy adversary, believes a CPI-M leader unwilling to be named.

The once invincible communist party is now waiting for TMC to crack open from within to gain in popular votes.
