Siliguri (West Bengal): Accusing the Mamata Banerjee led Trinamool Congress government of competing in vote bank politics, BJP's prime ministerial candidate Narendra Modi Thursday said the West Bengal government has betrayed the people's faith.

Modi also ridiculed Banerjee, saying the "parivartan" (change) brought by the Trinamool was fake. He was addressing a rally at Matigara in Siliguri city.
