Actor Lynda Bellingham, who found fame in the 80s as the mum in the Oxo adverts and now presents ITV1 chat show Loose Women, is appearing in an awareness-raising film for disability charity Action For Kids.
She introduces the six-minute film, which follows families the charity has helped by supplying mobility equipment and family support services.
"As a parent, you work towards achieving your children's full potential," says Bellingham. "Action For Kids does this for thousands of young people, helping to give them the confidence and independence to fulfil their roles in society."
Young disabled people involved in the charity's Work Related Learning scheme, which develops skills that are transferable to employment, helped with the production. The film will appear on the charity's website later this year.

Alison Steadman, the film and television actor who plays Pamela in BBC Three comedy Gavin and Stacey, hosted a reception last month for St Catherine's, a national charity that works with young people with speech, language and communication impairments.
The charity approached Steadman to ask for her support because of her acting experience. At the event, held at the British Academy of Film and Television Arts in London, she spoke about the challenges faced by children with communication disabilities.
"We wanted someone who uses communication in their professional life," says Suzanne Hudson, director of development at St Catherine's. "Alison is a great example because she has a remarkable ability to communicate well across a range of mediums: film, TV and theatre. She can bridge the gap in understanding between those with speech, language and communication difficulties."
