"None of the above" (NOTA), or none for short, also known as "against all" or a "scratch" vote, is a ballot option in some jurisdictions or organizations, designed to allow the voter to indicate disapproval of the candidates in a voting system. It is based on the principle that consent requires the ability to withhold consent in an election, just as they can by voting "No" on ballot questions. It must be contrasted with "abstention", in which a voter does not cast a ballot.

Presidential elections were held in Bulgaria on 6 November 2016, alongside a referendum on changes to the electoral system and political party funding. The second round was held on 13 November 2016, resulting in the victory of Rumen Radev.
