Seán Dermot Fintan O'Leary is an English-Irish broadcaster who currently works for ITV and BBC Radio 2. His radio career began when he worked as a disc jockey at Essex Radio, but he is best known for being the presenter of The X Factor (UK) on ITV, a position he held from 2007 until its final series in 2018, with the exception of 2015. Since 2021, O'Leary has presented ITV's This Morning on a Friday, School and Bank Holidays alongside Alison Hammond.
O'Leary started as a disc jockey at BBC Essex, based in Southend-on-Sea, before becoming a runner on the TV show Light Lunch with Mel Giedroyc and Sue Perkins and then a presenter at Channel 4 as part of the original presenting line-up of the channel's T4 strand, before moving on to present Big Brother's Little Brother (the companion show to Big Brother) on E4 from 2001 onwards. Also in 2001, O'Leary appeared on Lily Savage's Blankety Blank. In 2004, Dermot hosted the TV show Shattered.
On 29 March 2007, it was announced that O'Leary would replace Kate Thornton as the new host of ITV's The X Factor for at least two series. On 27 March 2015, O'Leary confirmed that he had quit The X Factor after eight years to pursue other projects. Via his Twitter account, he said:
Good afternoon. After eight wonderful years on The X Factor it's time for me to move on. I'd like to thank ITV, Simon, The X Factor family and particularly the viewers, all of whom have been a big part of my life for so long. I'd like to wish the team all the best for the future, especially whoever takes over from me.
O'Leary was replaced by Olly Murs and Caroline Flack, who previously co-hosted The Xtra Factor, the behind-the-scenes companion programme, together in 2011 and 2012.
On 29 March 2016, O'Leary returned to The X Factor as a presenter, replacing Murs and Flack, for the show's 13th series. In a statement, he said:
"I'm very flattered to be asked back to The X Factor, and am currently dusting off my dancing shoes. There is nothing more exciting than hosting live TV on a Saturday night. The show is naturally very close to my heart, after having hosted it for 8 years. I’m really looking forward to it, and excited to be back."
From 2010 to 2019, O'Leary presented the National Television Awards for ITV. Since 2010, O'Leary has hosted Soccer Aid on ITV, a celebrity football match in aid of the charity Unicef. In 2011, O'Leary hosted the Saturday night entertainment show The Marriage Ref on ITV. In September 2013, O'Leary hosted BRITs Icon: Elton John, a one-off music celebration for ITV.
In 2013, O'Leary presented the ITV campaign From the Heart, which encouraged viewers to consider organ donation. In January 2014, O'Leary filled in for Phillip Schofield for a week when he guest presented This Morning opposite Holly Willoughby.
In 2017, O'Leary co-presented the 37th BRIT Awards with Emma Willis. In March 2017, O'Leary guest-presented nine episodes of The Nightly Show on ITV.
In November 2020, it was announced that Eamonn Holmes and Ruth Langsford had been dropped from their Friday slot on This Morning after 14 years. Alison Hammond and O'Leary were announced to takeover the slot later that month. They presented their first show in January 2021.
On 27 November 2007, it was announced that Big Brother: Celebrity Hijack was to be O'Leary's last series of Big Brother, and that he would not return in summer 2008. After seven years, he made his final Big Brother appearance on 28 January 2008.
In March 2007, O'Leary signed a year-long contract with Channel 4 to appear on Hollyoaks. However, this was shortened after a series of disputes on set. Jim Rowe, a series writer at the time, said, "He couldn't follow even the simplest commands. It goes to show how vastly different presenting is to acting". O'Leary hasn't acted since. In 2009, O'Leary presented an episode of The Paul O'Grady Show, standing in for Paul O'Grady.
In March 2014, O'Leary made a return to Channel 4, where he presented the Live From Space season for three consecutive nights.
O'Leary was a presenter for Comic Relief in 2005, 2011 and 2013. He also presented Sport Relief in 2012. In August 2006, O'Leary signed a deal to present the game show 1 vs. 100, which aired on Saturday nights on BBC One in combination with The National Lottery Draws.
In May 2009, O'Leary became the presenter of Matt Lucas and David Walliams's show Rock Profile on BBC.
In March 2010, O'Leary hosted a spin-off edition of the BBC One show Question Time aimed at first time voters, which aired on BBC Three. He also presented Dermot Meets..., a series which saw him interview the likes of David Cameron, Gordon Brown, and Nick Clegg.
In November 2015, O'Leary replaced Terry Wogan on Children in Need due to Wogan's cancer-related ill health, from which he died a couple of months later.
In 2016, O'Leary presented the BBC One Saturday night game show The Getaway Car. The series was filmed in November 2015 and began airing in January 2016. He has also guest-presented two episodes of The One Show with Alex Jones.
O'Leary joined London's indie rock station XFM in 2001, firstly presenting weekday mid-mornings from 10 am to 1 pm, before moving to a Saturday evening show in mid-2002, where he remained until late 2003.
O'Leary joined BBC Radio 2 in September 2004, presenting a Saturday afternoon show titled Dermot's Saturday Club, which ran from 2 pm to 4 pm. Following a number of changes to the length and timing of O'Leary's programme, due in part to the arrival of Chris Evans to Radio 2 and his role as presenter of The X Factor, his show was broadcast between 3 pm and 6 pm from April 2009 until its end on 21 January 2017. It focused on new music and had featured live sessions from the likes of Oasis, Supergrass, the Raconteurs, Massive Attack, Kasabian, the Guillemots, Beck, Lily Allen, Foo Fighters, Bloc Party, and Kate Nash.
