Power of Veto

The Power of Veto is a power that was first introduced in Big Brother 1 (US) before being adapted by other franchises.

United States
The Power of Veto 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 the three guaranteed players. Powers of Veto may be won under rare occurrences besides competitions, such as as a prize to come from Pandora's Box.

Golden Power of Veto
The Golden Power of Veto was the Veto introduced at the start of Big Brother 1 (US) and has been used in every succeeding season. The Golden Power of Veto allowed the winner to remove one nominee off the Nomination Block if he or she so desired, including themselves. If the Veto were used, the HOH would select the replacement nominee.

The Power of Veto Contestant Selection
When the Power of Veto was first introduced in Big Brother 1 (US), the Head of Household and the two nominees still compete, but rather than selecting their own players, each would reach into a bag filled with small discs with a houseguest's name or the words "Houseguest's Choice", where the player who draws the ball disc gets to choose the additional player. The six houseguests later play in a competition to determine the winner of the Power of Veto.

The Power of Veto Meeting
The winner of the Power of Veto is called to the Diary Room, where they are briefed on the procedures of the Power of Veto meeting. The Veto holder then proceeds to the Memory Wall, retrieves the Veto, and studies the portraits of all the remaining houseguests as he or she finalizes his or her decision. The Veto holder then calls in the remaining houseguests who await the meeting in the backyard. The houseguests take their respective seats, either on the couches or on the Nomination Block. The Veto holder begins the meeting by explaining what powers the Veto holds and then asks the nominees to make a final plea, if they so desire, to try and convince the Veto holder to use the Veto on them. Once the nominees have made their speeches, the Veto holder makes his or her decision. If the holder chooses to use the Veto, he or she places the Veto around the neck of the nominee he or she has chosen to save. At this point, the Veto holder takes a seat, and the Head of Household stands and chooses a replacement nominee. If the Veto is not used, the holder places it in a box on the coffee table. After all the decisions are made, the Veto holder adjourns the meeting by closing the box shut.
