NEW DELHI: Bharatiya Janata Party (BJP) president Amit Shah on Tuesday criticised West Bengal chief minister Mamata Banerjee 's policies alleging that the Trinamool Congress (TMC) has undermined democracy in the state.Addressing a rally in Malda, Shah said that the TMC had left the same people helpless who brought it to power toppling the Communists."Today the situation is such in the state that people feel Communists' rule was preferable over TMC's. The government has murdered democracy in the state," said Shah.He added that the 2019 Lok Sabha elections will decide if the TMC government "...which is killing democracy, will remain in Bengal or will be uprooted."Training his guns at the Bengal chief minister, Shah said that the BJP will not stop its fight against the TMC misrule in the state even if the state government uses strong arm tactics."If Mamata didi will not let us organise the Rath Yatra, then we will organise a rally. If they will stop our rally, we will walk door-to-door," said Shah.Raking up the issue of infiltration which is a hot-potato in the state, Shah said that the BJP will stop infiltrators."I am assuring you, bring BJP and we will not let any infiltrators enter Bengal. But these people love infiltrators, that is why they go against us when we talk about NRC," said Shah.The BJP president said that where " Rabindra Sangeet used to play, bomb blasts fill the air.""The BJP shall bring the glory back to Bengal. This is what a real speech from a leader sounds like," said Shah.
