The Walking Dead star Lennie James has joined Barnardo's as the charity's first Children In and Leaving Care ambassador.

The British actor, who went into care with his brother at the age of ten, after his mother died, visited Barnardo’s YouthBuild Academy in Lewisham last week, where he met care leavers learning construction skills, and said 'The fear and vulnerability of going into care is etched in my memory. What made the difference was the support of those who looked after me... I was lucky to become an actor - if children have a stable and loving experience while in care, and then get the right support when they leave the system, they can go on to achieve and have fulfilling lives'.
