David Harewood and Linda Robson, known respectively for their roles in Homeland and Birds of a Feather, have lent their support to the British Lung Foundation's campaign to ban smoking in cars when children are present, by voicing toddlers in online videos.

Robson says 'We've already introduced a ban on smoking in public places to protect workers from second-hand smoke. Surely we can take this small step to protect our children too?'.
