Campaigners will stage a demonstration outside County Hall in Oxford in a bid to save three respite centres for disabled children.

More than 100 children will be affected if the county council goes ahead with a proposal to withdraw a £500,000 grant from Barnardo's, which runs the centres for five to 17-year-olds in Abingdon, Banbury and Henley.

The grant is part of a £9m package of cuts in social services agreed by county councillors earlier this year.

Margaret Coombs, from the Oxfordshire Community Care Advice and Action Group, said: "There will be a strong lobby outside County Hall. It's crucial that these respite centres do not close.

"We will also be campaigning against other social services' cuts, which affect the elderly and other vulnerable members of society."

Barnardo's has warned that Summerfield Resource Centre in Abingdon, Sycamore House in Banbury, and the Chilterns Centre in Henley, will have to close without the grant. Parents have lobbied Oxfordshire MPs at Westminster, and they have agreed to try to help families in any way they can.

On Tuesday at the county council meeting, Labour councillor Barbara Gatehouse is to ask when parents can expect to receive a consultation document about the closure plans.

Fellow Labour councillor Margaret MacKenzie will also question the Conservative-Liberal Democrat administration on what alternative care could be made available, if the closures go ahead.

Colin Webster, a spokesman for parents' group FORCe (Friends of Resource Centres) whose son Daniel, eight, attends Summerfield, said: "Parents have not been given any consultation document and we want to know what's happening."
