In April 2015, Louis Walsh cited his desire to quit the show and return to management, and that it would take serious thought for him to return for series 12. He also revealed that he was in the dark about whom Cowell had the intentions of bringing onto the panel. On 14 May 2015, Walsh confirmed his exit from the show after 11 series on the judging panel, stating, `` The truth is I 've done it for 11 years ; I never thought I would even be on TV for four or five. To get 10 was great, to get 11 was amazing - I 'm not hanging around for them this year. '' He later continued, `` But I was n't sacked, I have n't been hired and I 'm not hanging around. '' On 16 June, Cheryl Fernandez - Versini was confirmed to be returning for her fifth series followed by new judges, series 9 guest judge and The Voice UK coach Rita Ora, and BBC Radio 1 DJ Nick Grimshaw, replacing Walsh and Mel B, who left the show after only one series. The new judges were met with widespread negativity across social media and the press, especially regarding the appointment of Grimshaw. Series 12 presenters Olly Murs Caroline Flack Rochelle Humes ( The Xtra Factor ) On 27 March 2015, Dermot O'Leary announced that he was quitting the show, after eight series, in order to pursue other projects.

They became the first duo to host the show. On 18 June 2015, it was confirmed that The Saturdays singer Rochelle Humes and Kiss FM DJ Melvin Odoom would be the new hosts of The Xtra Factor. The show 's announcer Peter Dickson announced his departure from the show on 28 July 2015. Dickson was later replaced by Redd Pepper for this series, who was only present for Judges ' Houses. However, on 30 October 2015, Dickson confirmed that he would return to The X Factor for the live shows.

The room auditions were scrapped and therefore, the format saw the return of the arena auditions. The auditions were originally scheduled to begin in Manchester on 6 July ; however, following the death of Cowell 's mother on 5 July, the first two days of auditions were postponed to 8 July. As a result, a new day of auditions was announced for 9 July, but this last - minute addition meant that both Ora and Flack were absent due to prior commitments, resulting in just three judges that day and Murs having to host solo. The first day of London auditions were scheduled to be recorded on 14 July, but were cancelled due to the aforementioned bereavement. Flack was also absent from filming on 15 July due to her filming the Love Island final in Spain. Grimshaw had to leave the evening sessions ( 15, 16, 17, 19, 20 July ) of auditions early due to the session over-running and his contract obligated him to have a certain amount of rest between finishing filming and being on BBC Radio 1 the following morning. Filming was delayed on 20 July due to Fernandez - Versini suffering a burns injury to her foot after stepping on some hair tongs. Cowell was absent from the first session on 17 July due to illness. Ora was again absent from filming on 22 July, due to performing a prearranged gig in Italy. Notable returning auditionees included Havva Rebke, who reached bootcamp in series 9 ; Monica Michael, who was controversially eliminated during the six chair challenge in series 11 ; and Rumour Has It, who reached judges ' houses in series 11 as an unnamed girl group created by the judges. Summary of judges ' auditions City Date ( s ) Venue Absent judges Manchester 8 -- 9 July 2015 EventCity Rita Ora ( 9 July ) London 15 -- 17 July 2015 The SSE Arena, Wembley Simon Cowell ( 17 July ) 19 -- 23 July 2015 Rita Ora ( 22 July ) Bootcamp Bootcamp took place from 27 to 31 July, and was recorded at The Grove Hotel, Watford, having taken place at The SSE Arena, Wembley every other series. The first challenge of bootcamp was to perform in groups of five acts, with a mix of at least three categories in each group, and perform a song from a list. The judges would decide immediately after each performance which of the 180 acts would pass the challenge and which would be eliminated. For the second challenge of bootcamp, the 93 successful acts were to perform a solo performance to the judges, who gave little or no feedback to them. At the end of the challenge, the judges decided on who would be successful and who would be eliminated. Grimshaw was absent from the second day of the challenge due to his commitments with BBC Radio 1, although partially assisted Cowell, Fernandez - Versini and Ora with their decisions via Skype video link. The 64 acts that passed through this stage went on to face the six - chair challenge. It was reported that the standard of auditions were so high that acts who got a `` yes '' from all four judges were not necessarily guaranteed a place at bootcamp. For the first time in X Factor history, viewers voted via hashtags on Twitter to determine which of the judges was allocated each of the four categories ( for example, # SimonBoys or # RitaGroups ). The judges learnt the result during the six - seat challenge. Cowell will mentor the Overs, Fernandez - Versini has the groups, Grimshaw will look after the boys and Ora is in charge of the girls. Bootcamp aired over two episodes on 20 and 27 September. Six - chair challenge The six - chair challenge took place on 1 and 2 September, at The SSE Arena, Wembley. 64 acts faced the six - chair challenge, with 16 in the Girls category, 16 in the Boys, 17 in the Overs, and 15 in the Groups. The challenge was broadcast on 4, 11 and 18 October. At the start of the challenge, the judges discovered which categories they would mentor : Ora was given the Girls, Grimshaw was given the Boys, Cowell was given Overs, and Fernandez - Versini was given the Groups. Tom Bleasby was originally put through, but it was reported on 12 October that he had withdrawn for personal reasons. On 15 October, it was announced that Mason Noise would replace Bleasby at Judges ' Houses. On 20 October, it was revealed that all the groups would undergo name changes due to copyright reasons.

Instead, the judges ' houses performances were pre-recorded in the scheduled destinations, with all of the contestants who made it to that stage of the competition brought to London afterwards to watch the performances and find out if they had made it through to the live shows during a live broadcast.

Controversies Bootcamp It was reported that before bootcamp, some contestants who were given three or four `` yes '' votes from the judges were sent emails from the producers of the show saying that they would not be attending bootcamp due to limited places and a higher standard of auditions. One contestant who received such an email said, `` I feel X Factor needs to be shamed for this shocking incident. They are playing with people 's lives. '' A spokesperson for the show said this was `` kinder and fairer than an immediate ' cull ' of singers on arrival at bootcamp, which has happened in previous series. '' Mason Noise During the six - seat challenge, after performing for his mentor Grimshaw, Noise ( born Mason Birnell ) complained that his audition was only broadcast for 47 seconds while other contestants were featured for up to 10 minutes. Cowell responded by saying `` You should feel lucky to be on this show. Why do n't you shut up ? '' and called Noise an `` arsehole ''. Noise was booed by the crowd before walking off the stage. Noise later told the Daily Mirror : `` ( Cowell ) lost control and it was uncalled for. Especially as all I was doing was saying an opinion. I think that no one has ever questioned him before and no one has questioned the format of the show. Something needs to change on that show. Listen to the kids, at the end of the day I have a lot of support on Twitter. '' On 12 October, Tom Bleasby had withdrawn from the show and consequently, there was a spare place at judges ' houses. On 15 October, Grimshaw announced that Noise would replace Bleasby at judges ' houses. Monica Michael Monica Michael issued an apology when, after being eliminated in week 3, she appeared to make a gun gesture with her hand and shouted `` bang, bang, bang ''. Viewers called her `` inconsiderate '' and `` offensive '', as it was not long after the November 2015 Paris attacks. Michael took to Twitter to say, `` I want to apologies for any offence caused on the @ TheXFactor tongiht. I was n't thinking beyond the moment & it was insensitive, sorry. ( sic ) '' Caroline Flack and Olly Murs Presenters Flack and Murs were criticised throughout the series. Flack 's absence from several auditions caused confusion and their lack of chemistry was criticised, with a source from the show saying, `` Bosses have been aware of the criticism aimed at Olly and Caroline over their lack of chemistry. They were expected to inject some fun and energy but that has yet to be seen. We 've seen this year 's line - up undertake a big shake - up and Olly and Caroline were considered to be a safe bet. '' It was also stated that Flack 's other commitments were discussed beforehand. A spokesperson said : `` Olly and Caroline have been great additions to the show, We 're very happy with them and look forward to them being centre stage when presenting on the live shows at the end of the month. '' However, when the live shows started, viewers called for the return of Dermot O'Leary and called the pair 's presenting `` awkward '' and `` cringe - worthy ''. They were criticised for `` awkward glances, long pauses and over-enthusiastic shouting '' and the hashtag `` # bringbackdermot '' appeared on Twitter. In week 3, Murs apologised after claiming that Michael had been eliminated when in fact the judges ' vote had gone to deadlock and the result was yet to be announced ; in any case, Michael was revealed afterwards to have received the fewest votes and was sent home. Murs said : `` I apologise to everyone tonight I made a massive f -- k up at the end. It was so tense ! ! I 'm still learning & hope that never happens again ! '' Isabel Mohan from The Daily Telegraph said, `` We were always dreading Flack and Murs taking over from Dermot O'Leary -- we knew they would n't be able to hack it live on primetime telly. Dermot could build up tension. Dermot could read autocues. Dermot could speak properly with no lazy talk of ' the bottom free '. And, most of all, Dermot did n't tell people they 'd been voted off before he was supposed to ! (... ) What an absolute shambles. '' O'Leary supported Murs on Twitter, saying it `` Happens to us all '' and `` live TV is a tricky old beast at times. '' References Jump up ^ Rackham, Jane ( 29 August 2015 ). `` The X Factor ''.
