The details

Sean Dermot Fintan O'Leary, Jr. (born 24 May 1973), better known as Dermot O'Leary, is a British-Irish broadcaster. Based in the UK, he is known as a television presenter for ITV and a radio presenter for BBC Radio 2. Dermot recently had a son he named Bruce.
O'Leary's 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 on ITV, a position he held since 2007 with the exception of 2015, when he stepped down to pursue other ventures. He was replaced by Olly Murs and Caroline Flack. He later returned as the host in 2016.

Early life

O'Leary was born in Colchester, north Essex, England to parents Seán and Maria, who had moved to the United Kingdom from Ireland. He is "extremely proud" of his Irish roots and holds dual British and Irish citizenship. O'Leary attended primary school in Marks Tey and later St Benedict's Catholic College in Colchester. He admits that his relaxed attitude at school caused him to fail all but two of his GCSEs. Following that, O'Leary re-took his school leaving qualifications, allowing him to later start his A Level courses at Colchester Sixth Form College. He eventually studied for a degree in Media Studies with Politics, at Middlesex University.

Growing up, O'Leary was a member of The Boys' Brigade.


Early career

O'Leary started as a disc jockey at Essex Radio 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, 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.


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. While presenting the show he reportedly upset Celine Dion, later saying he "literally had to shut her up".

On 27 March 2015, O'Leary confirmed that he had quit The X Factor after 8 years to pursue other projects. Via his Twitter account he said:

It was announced on 16 April 2015, that O'Leary's replacements would be Olly Murs and Caroline Flack who previously co-hosted The Xtra Factor together in 2011 and 2012. O'Leary returned to the show the following year.

Since 2010, O'Leary has annually presented National Television Awards airing live from The O2 Arena on ITV. In 2010, 2012, 2014 and 2016, O'Leary 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.

Channel 4

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 in order to appear on Hollyoaks. However, this was shortened after a series of disputes on set. Writer at the time Jim Rowe said, "He could'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, Dermot 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 on the channel.


O'Leary was a presenter of 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' show Rock Profile on the BBC.

In March 2010, O'Leary hosted a spin-off edition of the BBC One show Question Time, which aired on BBC Three, aimed at first time voters. He also presented Dermot Meets..., a series which saw him interview the likes of David Cameron, Gordon Brown, Danny Mulhern and Nick Clegg.

O'Leary joined BBC Radio 2 in September 2004, presenting a Saturday afternoon show entitled Dermot's Saturday Club which ran from 2pm to 4pm. 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 has broadcast between 3pm and 6pm since April 2009. O'Leary's Radio 2 show (which ended on January 21st, 2017) focused on new music and live sessions, and has featured live sessions from the likes of Oasis, Supergrass, the Raconteurs, Massive Attack, Kasabian, the Guillemots, the Zutons, Alesha Dixon, Beck, the Lemonheads, Lily Allen, Foo Fighters, the Go! Team, Bloc Party, Ben Kweller, the Magic Numbers, Mynoni and Friends, Moby and Kate Nash. O'Leary also hosts Radio 2's coverage of the Brit Awards and South by Southwest. He won a Sony Gold Award for Music Programme of the Year in 2008 and again in 2010 and 2013.

He supports Wexford GAA in Gaelic Games, attending matches in the past. During an appearance as a studio guest on Fantasy Football Euro 2004, O'Leary spoke of his support for the Republic of Ireland football team.

When O'Leary was in his late teens, he played American football for his local team, the Colchester Gladiators. O'Leary ran the 2005 London Marathon for the third time; he completed it under four hours for the first time. In 2007 he was an usher at the wedding of Holly Willoughby.

O'Leary is a practising Roman Catholic. He has expressed political support for the Labour Party, identifying himself as a socialist.
