With the Election Commission on Monday writing to the Assam chief secretary to furnish names of all IAS officers from 2010 to 2021 batches, several district election officers (DEOs) in the poll-bound state are likely to be changed. The state has 35 districts. A DEO is a senior administrative official, typically the district magistrate or collector, appointed by the Election Commission. Officials said the poll authority is not happy with the performance of various DEOs and wants to appoint new officials. Assam will face assembly polls on April 9 in a single phase. Votes will be counted on May 4.
