We all know Ant and Dec, or we think we do. But how much do they know about their own history?

Ant and Dec’s DNA Journey casts the famous duo in quite a new light (Sunday, 9pm, see our TV Guide for full details).

Over the years we’ve grown used to seeing Ant and Dec in "entertainment mode” on the shiny floors of the BGT and Saturday Night Takeaway studios or the I’m A Celeb jungle.

So this lovely two-parter, which follows the boys on a thrilling global quest to learn more about their roots and family history, offers a surprisingly fresh and poignant take on their backgrounds and also the powerful friendship that has been the cornerstone of their careers.

After the pals’ DNA is examined, genealogists and historians use the results to unveil some incredible and deeply moving stories about their ancestors, including Ant’s war hero great-grandfather.

They also get the chance to meet up with a host of strangers across the world who share their genes. Concludes tomorrow.
