Power of Veto

The Power of Veto (abbreviated POV) is a power that allows the owner to remove one of the Nominations from the Nomination Block. The Power of Veto also guarantees the holder safety should one of the nominees be removed, unless he or she is the only possible replacement nominee. The Head of Household chooses a new nomination.

The Power of Veto is won weekly in a competition. Six houseguests compete for the Power of Veto: the Head of Household, the two nominees, and three other houseguests chosen by a random draw.

Variants
Golden Power of Veto: The original variant of the POV, the Golden POV allowed the user to save one of the nominees from eviction and allow the HOH to renominate someone in their place.

Secret Power of Veto: Introducted in Big Brother 1, the Secret Power of Veto (SPOV) was a hidden Veto necklace that could only be grabbed by opening a door with a numerical code hidden throughout the house. It could be used after the POV ceremony and could be used as a regular Golden Power of Veto. Vince Camargo was the first to find the clues after the first eviction and opened the hidden door, where he was granted the SPOV. However, it expired before he ever got the chance to use it.
