McPartlin, 43, said: “I’m a bit of a geek when it comes to historical events, so to get the chance to research our family history using our DNA was too good an opportunity to pass up. What we find out is mind-blowing and nothing either of us could ever have imagined. It’s something that will stay with us both forever. "

The two-part show sees the Britain’s Got Talent hosts travel to Ireland and the US, including the United Nations Headquarters, where one learns that their great-grandfather is a celebrated war hero and one discovers that their ancestors’ bones are deemed “of historical importance”.

Donnelly, 44, said: “A huge part of this was to find out my heritage, especially on my dad’s side. I always thought I knew a fair bit about where I came from but it turns out I was wrong! Whilst it was incredible to find out about the past, what was hugely overwhelming was to meet relatives neither of us knew we had. It was a truly amazing experience."

In 2016 EastEnders star Danny Dyer found out he was related to Thomas Cromwell, Edward III, William the Conqueror and Henry III during filming for the BBC's genealogy show Who Do You Think You Are?

McPartlin returned to TV this year after taking a break following a conviction for drink-driving in 2018.

Ant and Dec’s DNA Journey is coming to ITV soon, with a date to air still to be announced.
