Gangtok, Aug 7 (PTI): Names of 37,724 people have been left out of the draft electoral roll in Sikkim as they have not submitted their enumeration forms during Special Intensive Revision (SIR) of rolls, an official said on Friday. Sikkim had 4,71,018 electors before the SIR of electoral rolls, of whom 4,33,294 Enumeration Forms were received and digitised, the official said. CEO Raj Kumar Yadav said around 77 per cent of electors had been successfully mapped with the 2002 electoral roll during the door-to-door exercise. The notices were primarily served to electors whose names could not be linked or mapped with the 2002 electoral roll, or whose details submitted in the enumeration forms required further verification. The final electoral roll is scheduled to be published on September 6.
