Responding to the delay over funding of elderly care, National Autistic Society chief executive Mark Lever said:
"This decision, affecting the lives of so many people, is just too important to keep putting off and playing politics with.
"At a time when social care is being cut, thousands of families are currently living in uncertainty and delays will do nothing to ease the anxiety that they feel.
"This is one of the biggest challenges currently facing us all and it's vital that we come together to find a timely and workable solution for some of the most vulnerable people in our society."
