FOR 20 years, Who Do You Think You Are? has traced the ancestries of our favourite celebrities, letting viewers watch as their incredible family secrets come to light.

The show has also inspired millions of ordinary people to investigate their own family trees, hoping to find links to royalty as the actor Danny Dyer famously did in Series 13.

As the BBC show marks its 20th anniversary, producer Collette Flight said Dyer's reaction when he found out that his 15x great-grandfather was Thomas Cromwell and that he was descended from Edward III, will stand as one of the show's best moments.

But she admitted it's impossible to pick one favourite revelation from the 161 episodes screened since 2004.
