Yercaud comes under the Salem district. No publicity should be given to any political party or candidate at the cost of public exchequer.
"Hence all advertisements by government are banned in the entire Salem district," a release from the office of Tamil Nadu Chief Electoral Officer Praveen Kumar said here.
"Also publicity given to any party in the form of distribution or sale of articles by government or government agencies, with the articles having pictures of political persons or symbols of any party is also covered by the Model Code of Conduct," it said.
EC has written to all government secretaries asking them to ensure that no sale or distribution of such articles by government or government agencies takes place in Salem district during the operation of Model Code of Conduct.
"Any violation of the same would be viewed very strictly by the Election Commission of India," it said.
The directives comes amid complaints by opposition DMK that the ruling AIADMK was misusing official machinery.
