Seán Dermot Fintan O'Leary, Jr. known as Dermot O'Leary (born 24 May 1973) is an English television and radio presenter of Irish descent, best known for his current television and radio work with ITV and BBC Radio 2.
His early television career saw Dermot present the spin-off show Big Brother's Little Brother on Channel 4 between 2001 and 2008, he also presented a number of other Big Brother spin-off shows including Big Brother Africa and Big Brother Around the World.
Since 2010, Dermot has annually presented National Television Awards airing live from The O2 Arena and airing on ITV, the awards were previously hosted by Trevor McDonald. In 2011, he hosted seven-part series The Marriage Ref for ITV.
O'Leary was born in Colchester, England to parents Sean and Marie, who had moved to the United Kingdom from the neighbouring Republic of Ireland. He is "extremely proud" of his Irish roots and holds dual British and Irish citizenship. He attended primary school in Marks Tey and later St Benedict's Catholic College in Colchester, where he graduated with two General Certificates of Secondary Education. He also attended Colchester Sixth Form College.
O'Leary studied at Middlesex University, achieving a degree in Media and Television with Politics. He achieved a 2:2. Whilst at Middlesex University he developed an interest in comedy and was involved in various gigs in the students' union. He was also a member of the university's chess society.
O'Leary started as a disc jockey at Essex Radio before becoming a runner on the TV show Light Lunch with Mel Giedroyc and Sue Perkins and then 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.
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.
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. Speaking after the announcement he said: "I was very flattered to be offered the job to host such a hugely successful show. I'm really looking forward to working with Simon Cowell and the team on the kind of Saturday night entertainment show I grew up watching." While presenting the show he reportedly upset Celine Dion among other things, later saying he "literally had to shut her up".
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. In June 2010 and May 2012, O'Leary hosted Soccer Aid on ITV, in aid of charity Unicef.
O'Leary joined London's Indie rock station XFM in 2001 firstly presenting weekday mid-mornings from 10 am–1 pm, before moving to a Saturday evening show in mid-2002, where he remained until late 2003.
He 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 focuses 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.
