Voting Substitute is a term used to describe a person who is authorized to cast a vote on behalf of another person. A PROXY (5 letters) is a person who is appointed to act as a representative for another person in a legal or business matter. This type of voting substitute is often used in corporate meetings, where shareholders are unable to attend the meeting in person but still wish to have their vote counted. In some cases, proxies may also be used in elections, allowing people to vote by PROXY if they are unable to attend the polling station.
