In a letter to Chief Election Commissioner V S Sampath, state Congress general secretary Khurshid Saiyed said the BJP government was openly "misusing" government machinery to influence voters.
Several state ministers, BJP MPs and MLAs are touring the poll-bound areas where they were not registered as voters.
"As per MCC, all outsiders should leave the constituencies by 6 PM today as campaigning has ended," it said.
The letter also sought that CEC should give appropriate directions for deployment of para-military forces at vulnerable polling booths.
