Introduction
Declan Donnelly is one of the best-known television presenters in Britain, recognised worldwide as one half of the hugely successful duo Ant & Dec. His career began when he was a child actor on the Newcastle-based drama Byker Grove, where he met Anthony McPartlin. The pair later became pop stars before establishing themselves as television presenters.
Decades after their first appearance together, Donnelly and McPartlin remain closely associated with some of ITV’s biggest entertainment programmes, including Britain’s Got Talent, I’m A Celebrity…Get Me Out Of Here! and Ant & Dec’s Limitless Win. ITV confirmed in December 2025 that their exclusive relationship with the broadcaster had been extended through the end of 2028.
Who Is Declan Donnelly?
Declan Donnelly is a British television presenter and former actor and pop performer from Newcastle upon Tyne. He is best known professionally as “Dec”, the younger-looking half of Ant & Dec alongside Anthony McPartlin.
The pair first met while working on Byker Grove, a children’s television drama filmed in Newcastle. Donnelly joined the programme in 1989 as Duncan Sperring, while McPartlin later joined the cast as Peter “PJ” Jenkins. Their friendship developed on and off screen, eventually becoming one of the UK’s most enduring television partnerships.
After leaving Byker Grove, the two continued working together as PJ & Duncan in music. Their single “Let’s Get Ready to Rhumble” reached number nine in the UK singles chart, giving them an early taste of mainstream success before they moved increasingly into television presenting.
Today, Donnelly is primarily recognised for his work as a presenter and producer, rather than for his early acting or music career.
Declan Donnelly’s Career
Donnelly’s career is unusual because it has successfully moved through several different areas of entertainment.
From Byker Grove to PJ & Duncan
The starting point was Byker Grove. Donnelly and McPartlin became closely associated with the programme and their characters, Duncan and PJ. Their success on the show provided the foundation for their later partnership.
They subsequently released music under the name PJ & Duncan. Although their recording career was relatively short compared with their television careers, it helped establish them as recognisable young entertainers.
The transition from acting and music into presenting was the crucial step. By the mid-1990s, the pair were hosting television programmes together, beginning a partnership that would eventually span decades.
Becoming Ant & Dec
Their television careers grew rapidly, and the name Ant & Dec became synonymous with mainstream British entertainment.
Among their best-known programmes are Ant & Dec’s Saturday Night Takeaway, Britain’s Got Talent and I’m A Celebrity…Get Me Out Of Here!.
The pair also developed Ant & Dec’s Limitless Win, a quiz and entertainment format built around a potentially unlimited money ladder. ITV reported that the programme attracted 6.1 million viewers for its launch episode in 2022 and was subsequently recommissioned.
Their presenting partnership has also survived periods when they have not been able to work together. In 2018, for example, Donnelly presented live episodes of Britain’s Got Talent on his own while McPartlin was away from television. ITV later reported that the pair reunited for the following series.
Saturday Night Takeaway
Ant & Dec’s Saturday Night Takeaway became one of the duo’s signature programmes. After two decades and 20 series, the pair announced that the 2024 series would be their last for the time being, describing the decision as a chance to take a break from a programme that occupied a substantial part of their year.
The decision did not represent an end to Donnelly’s television career. Ant & Dec continued their ITV relationship through programmes including Britain’s Got Talent, I’m A Celebrity and Limitless Win.
Long-term ITV relationship
The longevity of Donnelly’s television career is particularly notable. In December 2025, ITV announced a further three-year extension to its exclusive relationship with Ant & Dec, taking the arrangement through the end of 2028.
ITV said the pair would appear during 2026 in new episodes of Ant & Dec’s Limitless Win, Britain’s Got Talent, I’m A Celebrity South Africa and I’m A Celebrity…Get Me Out Of Here!. The broadcaster also reported that their ITV programmes had accumulated 688 million streams on ITVX and that the duo had won 48 National Television Awards and 18 BAFTA Television Awards as a presenting partnership.
That agreement demonstrates that Donnelly remains a major part of ITV’s entertainment strategy rather than simply relying on his historical success.
What Is Known About Declan Donnelly’s Personal Life?
Donnelly generally keeps his family life away from the level of exposure associated with his television career. Some basic details, however, have been publicly confirmed.
He married Ali Astall in Newcastle on 1 August 2015. Astall was Donnelly’s professional manager, and their wedding was attended by a number of television and entertainment figures. Donnelly’s brother, Father Dermott Donnelly, conducted the ceremony, while Ant McPartlin served as best man.
The couple have two children. Their daughter, Isla Elizabeth Anne, was born in September 2018.
In July 2022, Donnelly and Astall announced the birth of their son, Jack Anthony Alphonsus. The couple confirmed the news publicly through their shared social-media account.
The middle name Anthony is particularly notable because it is the first name of Donnelly’s long-time television partner, Anthony McPartlin.
Donnelly has experienced both significant personal happiness and loss during his adult life. His older brother Father Dermott died in July 2022 after a short illness. He had played an important role in Donnelly’s family life and had also conducted Donnelly’s wedding ceremony.
Declan Donnelly and Ant McPartlin: Why Their Partnership Has Lasted
The relationship between Donnelly and McPartlin is central to understanding Donnelly’s career.
They met as teenagers through Byker Grove and gradually moved from acting to music and then television. Their partnership has remained unusually consistent, even as the entertainment industry around them has changed.
Their appeal has partly come from their contrasting but complementary on-screen personalities. Rather than presenting as two completely separate television personalities, Ant & Dec operate as a recognisable double act whose chemistry is part of the entertainment.
Their friendship has also been tested by difficult periods. When McPartlin temporarily stepped away from television in 2018, Donnelly continued with several programmes rather than abandoning their shared commitments. The two subsequently returned to presenting together.
Their long history is one reason Ant & Dec remain more than simply co-hosts. They have effectively built a joint television identity while also developing individual lives and responsibilities outside the screen.
What Do Reliable Sources Confirm?
When looking at information about Declan Donnelly online, it is useful to distinguish established facts from celebrity speculation.
Confirmed facts include:
- Donnelly and Anthony McPartlin first became known through Byker Grove.
- They later worked together as the pop duo PJ & Duncan before concentrating on television.
- Donnelly married Ali Astall in 2015.
- The couple have two publicly acknowledged children, Isla and Jack.
- Donnelly and McPartlin have presented major ITV programmes including Britain’s Got Talent and I’m A Celebrity…Get Me Out Of Here!.

By contrast, online claims about private finances, undisclosed relationships or other personal matters should not automatically be treated as fact. Unless such information comes directly from Donnelly, his representatives or a reputable publication with clear evidence, it is safer to regard it as unconfirmed.
