The campaign which launched last year demands that Government reinstates £434 million to families and services for disabled children which were lost in funding cuts.
Martin, who is a patron of Julia’s House Children’s Hospice, said of DCP's findings: "A report has just been carried out into the economic impact of parents not having respite care.
"It costs the Government and local authorities more if it is NOT given because families buckle under the strain."
He added: "Right now, six out of ten families don’t get any respite breaks at all, and of those that do, three-quarters of them have lost these breaks during lockdown.
"I wholeheartedly support the need to improve funding for this life-changing care for families – I’ve seen the difference it makes to families at breaking point."
