The symbol approved is a circular depiction with black background and NOTA written in white in capital letters in English.
NOTA will be printed in addition to "None of the above" in the row of symbols. This time it will be one of the 16 buttons in the electronic voting machine.
The depiction will remain the same in all the ballot papers, whatever be the language of it.
"We are trying our best to popularize the "none of the above" button with the name of NOTA, so that the voters do not get muddled regarding it," said Delhi election commission's chief nodal officer Ankur Garg.
The NOTA button also known as "against all" is a ballot option designed to allow the voter to indicate disapproval of all of the candidates in a voting system.
