The X Factor (British TV series) series 15
The fifteenth and final series of the British television music competition The X Factor began airing on ITV on 1 September 2018, presented by Dermot O'Leary. Simon Cowell returned alongside new judges Louis Tomlinson, Ayda Field, and Robbie Williams who replace departing judges Nicole Scherzinger, Sharon Osbourne, and Louis Walsh. Nile Rodgers filled in for Williams while he was away on his tour for weeks 3–5 of the live shows.
On 2 December, Jamaican-born singer Dalton Harris won the series making him the first and only foreign contender to win the UK show. This was the only series that featured Tomlinson, Field, and Williams as judges.
After this series, the show was put on a 'break' and in 2019 the show was replaced by a Celebrity spin-off and a Band spin-off. In 2020, it was announced that the show was still on a 'break'. However, in July 2021, it was confirmed that the show has been officially cancelled after 17 years.
Judges and Presenters
On 6 June 2018, it was announced that Sharon Osbourne would return to judge the fifteenth series, but only for the live shows, due to her ongoing work commitments in the United States. The next day, long-serving judge Louis Walsh announced that after thirteen years on the show, he would leave to focus on other projects. Earlier in the year, it was reported that Nicole Scherzinger would not return as a judge for the fifteenth series.On 30 September 2018, Osbourne announced her decision to no longer appear as a judge during the live shows, stating that she had "seen the new judges finding their rhythm and are doing brilliantly".
Simon Cowell confirmed his return as head judge and Dermot O'Leary’s return as presenter. After much speculation, it was announced on 16 July 2018 that Ayda Field, Robbie Williams and Louis Tomlinson would join Cowell on the series' judging panel to replace Osbourne, Walsh, and Scherzinger respectively. On 17 October 2018, British DJ Jonas Blue confirmed that he auditioned for a judge position and was ready to take part in the series until prior gig commitments caused a clash in scheduling. He was later replaced by Tomlinson.
On 23 August 2018, it was announced that Xtra Bites would return after a first series, presented by Becca Dudley again, and she would be joined by a co-host named Tinea Taylor.
On 2 November 2018, it was revealed that Nile Rodgers would fill in for Williams on the panel during some of the live shows, due to Williams' touring commitments. Rodgers sat alongside Williams on 3 November, before fully substituting for him on 4, 10, 11 & 17 November. In a statement, Rodgers stated: "I had such a great time with Louis at the Judge's House in Ibiza a couple of weeks ago that when the opportunity came to step in for Robbie I could not say ", "From Chic and Sister Sledge to Duran Duran and Daft Punk, I've had great experiences with Groups in my career, so I look forward to giving them as much support as I can while Rob is away!". Williams returned to the panel on 24 November.
Selection process
Auditions
Auditions for performers took place only at London's SSE Arena, Wembley, on 18–20, 22–24 and 26–28 July 2018.Deliberations
Instead of the traditional bootcamp stages, a deliberation stage was introduced to cut down the number of performers at the six-chair challenge. This took place on 30 July 2018 at the Tobacco Dock in London. It was broadcast on a single episode on 23 September 2018 after the final auditions show.After the "deliberation" and "reveal" stages, but before the start of the "six-chair challenge", the judges found out the categories they are mentoring: Cowell mentored the "Girls", Field mentored the "Over 29s", Williams mentored the "Groups", and Tomlinson mentored the "Boys".
Six Chair Challenge
The Six Chair Challenge took place over the course of three days, from 1–3 August 2018, at the SSE Arena in Wembley. A new twist was added with the introduction of a golden button, similar to Got Talents Golden Buzzer. When this was pressed, the act in question was guaranteed a 'Safe Seat', and would go straight through to Judges' Houses. The Six Chair Challenge was aired over 3 episodes starting on 29 September 2018 and finished on 6 October 2018.During this stage of the competition, Williams called back five soloists from the Boys category who had been rejected during the deliberations, and asked them to form a new five-piece boyband, Vibe 5. After two American singers, Panda Ross and Burgundy Williams, had lost their seats after auditioning for Field's Overs category, Williams called them back to reaudition as a duo in the Groups category.
Judges' Houses
It was announced by O'Leary during an appearance on This Morning that the Judges' Houses would be filmed in late September 2018, and that three of the judges' houses would be in Los Angeles ; Tomlinson's houses would be hosted in Ibiza. Cowell judged from Malibu, while Field and Williams each judged their categories separately from their home in Beverly Hills. The guest judges were announced to be including American Idol alumnus Adam Lambert and Series 3 winner Leona Lewis in assisting Field, David Walliams with Williams, and Cowell's American Idol colleagues Paula Abdul, Randy Jackson and Ryan Seacrest along with Diane Warren, Babyface, Lewis and Sinitta to assist Cowell, who hosted a house party consisting of various singers, songwriters and record producers for the Girls to perform in front of. Tomlinson was assisted by his One Direction bandmate Liam Payne and Nile Rodgers.Maria Laroco was not able to secure the correct visa in time to travel to Malibu with the remaining Girls for this stage of the competition. Unlike similar instances where the affected contestants withdrew from the competition, Laroco sang to Cowell via video link from a London studio. 16 contestants were put through to the live shows at this stage, four from each category. This last-minute change was lobbied by Cowell who was unable to narrow his Girls down to just three; the other judges were then allowed one more act each for their own categories as well.

Controversies
Accusations of transphobia
During the audition stage, 20-year-old transgender man Felix Shepherd impressed the judges with his rendition of "All I Want" by Kodaline, and received a standing ovation from the crowd. Before singing, Williams asked him about his background; Shepherd said he was there to prove to people that he was "more than just a transgender guy." Williams responded by asking him: "So when you were born, what was your name?", thus misgendering him. Although many fans of the show were supportive of the representation, many were outraged by Williams' question, though Shepherd stated that he was not offended by Williams.Sharon Osbourne
On 5 September 2018, whilst on Howard Stern's radio show, Osbourne accused Cowell of underpaying her for the new series. She used some offensive language to criticise Cowell and the show's auditionees, which led to a backlash from fans who suggested that Osbourne should be replaced. Osbourne subsequently announced her decision to not participate during the live shows.Various sources reported that Osbourne had been fired over the interview and Stern stated that he believed she had been tipped off to keep quiet. Osbourne later refuted Stern's allegations and stated that her comments were only made in jest and were not to be taken literally, but that they were misappropriated by other people including The X Factor’s production company due to Stern wanting to give Cowell a bad reputation by using his radio show. She added that although the company wanted to fire her, Cowell was not upset with the comments and wanted her to remain on the show, but that it was ultimately her decision to step down out of fear of awkwardness between her and fellow judges Williams and Field, with whom she is close friends, though she did not rule out a return to the show in the future.
