Broadchurch and Peep Show actress Olivia Colman has recorded a BBC Radio 4 appeal in support of The Anthony Nolan Trust, as the charity celebrates its 40th anniversary.
Colman said 'Anthony Nolan cures blood cancer every single day. But for every person Anthony Nolan helps, there is another they can't help because no matching donor can be found, so it couldn't be more important to keep spreading the word'.
