It is comical my mother has just phoned me as the doctor has phoned about a form they received about council tax (she has challenged paying full amount) she now has to find out paperwork proving she is registered disabled, the doctor is not sure why they get sent the form and why the council can’t go direct to dwp. I will now have to do a 200 mile round trip to put her mind at rest and look for the said paper work.
So YES a Disabled ID Card would get my vote! (For many reasons not just this example)
