Kolkata, Oct. 30 -- Trinamool Congress national general secretary Abhishek Banerjee sharpened his attack on the Bharatiya Janata Party and the Election Commission of India on Wednesday over the special intensive revision (SIR) of electoral roll in West Bengal hours after a 60-year-old farmer attempted suicide in Cooch Behar district allegedly out of fear that he might be branded as a Bangladeshi infiltrator and deported. The man survived after being rushed to hospital. The Cooch Behar incident happened a day after a 57-year-old man died by suicide on Tuesday in North 24 Parganas district's Agarpara, leaving a note holding the National Register of Citizens (NRC) responsible. "Can any of the Union ministers, including the Prime Minister, show us the birth certificates of their parents and grandparents? Does the name of Chief Election Commissioner Gyanesh Kumar's father exist in voters' list? Did (Union home minister) Amit Shah's father have a birth certificate?" Banerjee said after visiting the home of the Agarpara victim, referring to documents a voter not enlisted in the 2002 electoral roll has to provide during SIR. Coming hours after the EC announced the second phase of the SIR in 12 states and union territories, including poll-bound Bengal, the Agarpara man's death triggered a row. "This morning, another man tried to commit suicide at Dinhata in Cooch Behar district by consuming pesticide. He has been rushed to hospital. These back-to-back incidents cannot be called coincidence. Amit Shah and Gyanesh Kumar are responsible for these," Banerjee said....
