Big Brother 2023, also known as Big Brother 20, is the twentieth series of Big Brother to air in the United Kingdom. It is the first series to air on ITV2 after ITV gained the rights to the series in August 2022, almost four years since it last aired on Channel 5. The series began on 8 October 2023, with a launch show airing simultaneously on both ITV (ITV1 and STV) and ITV2, with the remainder of the series broadcasting primarily on the latter channel. It is co-presented by AJ Odudu and Will Best, who also front the companion show, Big Brother: Late & Live.

On 17 November 2023, Jordan Sangha was announced as the winner of the series, beating Olivia Young who finished as runner-up. At 42 days, this was the shortest-running regular series of Big Brother in the UK, surpassing the seventeenth series, which lasted 50 days. This was surpassed by the succeeding series, which ran one day shorter.

Format Following the commissioning of the show, ITV announced that the series would feature a new cast of carefully selected housemates, from all walks of life. The series is set to run for up to six weeks, with "cameras capturing [the housemates'] every move, and the nation following every twist and turn." Shopping tasks, nominations and live evictions returned, with the public once again voting throughout the series and ultimately determining the winner, who would walk away with a £100,000 cash prize.

Housemates On 7 October 2023, a day prior to the airing of the launch show, the Big Brother social media accounts posted close-up teasers of the sixteen housemates' eyes.

Notes

: Olivia was initially nominated for eviction after being chosen as the hardest housemate to live with by Jenkin in the Launch Night twist. She later won immunity after not being ranked the least entertaining. : This week housemates were required to nominate only one housemate for eviction instead of two. : As a punishment for discussing nominations, Yinrun's nominations were voided. : As part of the Halloween task, Noky became "possessed." She then had to select one housemate to help decide which three housemates would be nominated for eviction. Noky chose Trish. A flash vote was held on Day 24, during Big Brother: Late & Live, and the evicted housemate left through the back door. : For Day 28's double eviction, the four or more housemates with the most nominations faced the public vote. : On Day 29, as part of the Hunger Games task, Chanelle was chosen to be given immunity by her winning team, while Jenkin was chosen to be nominated by his losing team. As a punishment for discussing nominations, Chanelle's immunity was later revoked and Olivia was banned from nominating. : On Day 37, housemates nominated face-to-face and the three housemates with the most nominations were "fake evicted". As a rule of the face-to-face nominations three housemates had to be nominated, as the housemates with the least nominations Matty & Yinrun had to break the tie between Henry, Noky, Olivia & Tom. Unbeknownst to the remaining housemates, the evictees moved Next Door and a public vote would result in two housemates being evicted and the surviving housemate re-entering the house. : On Day 39, the voting lines opened for the public to vote for the winner. On Day 40, voting was frozen and Matty, the housemate with the fewest votes, was evicted via the back door. The voting percentages for the finalists reflect their overall share of the final vote, and do not reflect the regular voting freezes that took place during the final. Jordan won with 65.22% of the vote over Olivia's 34.78%.

Weekly summary The main events in the Big Brother 20 house are summarised in the table below. Week 1 Entrances On Day 1, Jenkin, Farida, Tom, Hallie, Trish, Yinrun, Jordan, Zak, Chanelle, Dylan, Noky, Matty, Paul, Henry, Olivia and Kerry entered the house. Twists On Day 1, Olivia was automatically nominated to face the first eviction by Jenkin. Later, Big Brother revealed that she would have the chance to win immunity if she was not ranked least entertaining in the next task. On Day 2, she ultimately was not ranked least entertaining in the task and earned immunity from this week's eviction. Nominations On Day 6, housemates nominated for the first time. This time, however, the housemates only had to nominate one housemate for eviction. Farida and Kerry received the most nominations and therefore faced the public vote. Tasks On Day 1, throughout launch night housemates took part in a variety of party games. The first was "Musical Statues", and as Yinrun was the winner she rewarded with breakfast in bed and had to choose one housemate to prepare it for her the next morning; she chose Jenkin. The housemates were then told they were playing "Hide and Seek" and had to hide in an area of the house. Upon Matty's entrance, he had to declare which housemate he found first, which he said to be Jenkin, who subsequently lost privileges to hot water for the next 24 hours. Once all housemates had entered, they took part in "Pass the Parcel" and each layer contained a question. Paul was asked which housemate he would least like to share a bed with; he chose Dylan who was then forced to sleep on the floor. Kerry was asked which housemate she thought had the "Most Questionable Dress Sense"; she chose Jenkin who therefore lost access to his suitcase. Jenkin was asked which housemate he thought would be the "Hardest to Live With"; he chose Olivia who was told she would face the first public vote. On Day 2, housemates took part in a task where they would rank each other based on various characteristics. However, Olivia was given a secret mission to earn herself immunity from the first eviction. Olivia was told that she would have to not be ranked least entertaining to earn herself immunity. She ultimately was not ranked least entertaining, and earned herself immunity from this week's eviction. On Day 3, housemates took part in a task where they had to last the longest laying on an oversized bed. Dylan, Matty, Paul and Zak lasted the longest and won themselves a private cocktail party. On Day 4, the housemates took part in their first shopping task "Big Bro's Ltd", in which the housemates were split into a hierarchal format in an office and had to complete various tasks within the company. Henry, Trish and Yinrun served as the "Big Wigs", followed by Farida, Jordan, Kerry, Matty and Zak as "Middle Management", ultimately leaving Chanelle, Dylan, Hallie, Jenkin, Noky, Paul and Tom as the "Bottoms". Jordan was appointed "Fire Warden" and had to guide the housemates through an evacuation procedure which they had to complete within a certain time limit, housemates successfully followed the procedure twice and passed this part of the task. Throughout the duration of the task, the "Bottoms" had to separate paper clips. For the next part of the task, Paul and Zak visited "BB's Post Room" in which they had to organise letters by using the map and placing them in the correct pigeon hole, however they were unable to complete the task to Big Brother's satisfaction and failed this part of the task. Paul was later promoted to "Middle Management" and Farida was demoted to the "Bottoms". The next task consisted of Kerry and Noky visiting the "Finance Department" where they had to count the amount of coins that fell down a chute, to which they succeeded. For the final part of the task in the I.T department, "Bottoms" Olivia and Tom had to untangle wires to find the correct plugs and hand them to Matty in "Middle Management" who would place the plug in the correct socket, all whilst receiving electric shocks. The housemates passed the shopping task on Day 5 after successfully completing four out of five tasks, and were subsequently rewarded with a luxury shopping budget. Exits On Day 7, Farida became the first housemate to be evicted. Week 2 Nominations On Day 11, housemates nominated for the second time. Housemates were now required to nominate two housemates for eviction instead of one in the previous week. Henry and Zak received the most nominations and therefore faced the public vote. Punishments On Day 12, as punishment for writing secret messages on each others backs and discussing nominations, Hallie and Olivia were sent to jail in the garden. On Day 13, Hallie received a further punishment from Big Brother for her discussion of nominations, and was forced to wear a sign with "Warning: Rule Breaker" written on it, as well as a cone hat. Tasks On Day 8, Chanelle was given a secret mission to give backhanded compliments to the other housemates. She passed her secret mission and won the housemates a huge jar of sweets.
