The role comes in recognition of his substantial support of the charity’s campaigns and fundraising activities.
Farleigh’s support of Action for Children’s work with vulnerable children and young people is motivated by being fostered himself as a child, after experiencing poverty, violence and neglect in the Australian outback.
His desire to encourage more people to consider fostering or adopting children led to his relationship with Action for Children, and his spearheading of the charity’s campaigns to help children in care.
Richard will be taking part in Action for Children’s million-pound fundraising event, Byte Night, this October by sleeping rough for the night in London and raising vital funds for the charity’s community-based services.
Sir Tony Hawkhead, chief executive of Action for Children, said: “We are delighted to welcome Richard as our new Ambassador.
“He has already done a great deal to support our work, dedicating his time to help thousands of children looking for a loving home.
“We look forward to working with him closely in the future and know that he will play an invaluable role.”
Richard Farleigh said: “I know from experience that the right support can transform a child’s life.
“Action for Children helps children and young people to reach their potential even if life has put barriers in their way.
“I am proud to become their newest Ambassador, and am excited to be involved in its essential work to give children and young people the support they need.”
Richard will be sleeping rough in London to raise money for Action for Children as part of the Byte Night event, the UK’s biggest sleepout taking place in eight cities this October.
