The Children's Society reports that disabled children who do not live at home should have the right to an advocate who can speak on their behalf.

Although the organisation says that more than 13,000 children placed away from home are at greater risk of abuse, only 5 per cent of them have access to an independent advocate.

The society's strategy director says that disabled children are often denied basic rights like choosing what to eat and when to go to the toilet.

An Ipsos MORI survey was commissioned by the society to reinforce its message that all disabled children in residential or foster care need the services of an independent spokesperson.

The survey suggests that the public overwhelmingly supports its aim, with more than 80 per cent agreeing that advocates are necessary.

Three-quarters of the more than 2,000 people interviewed also felt that more needed to be done to improve support for disabled children.

"Every child deserves a good childhood and disabled children placed away from home should have access to an independent advocate to safeguard this entitlement," said Children's Society strategy director, Penny Nicholls.
