Welfare Reform and Work Bill

My Lords, I ask for a little clarification. I was somewhat astonished by my noble friend Lady Meacher referring to patients with multiple sclerosis, motor neurone disease, Parkinson’s, and diseases that can in fact be terminal. I understand that there is a distinction between the point at which people are diagnosed and the point at which they might be assessed as being able to work, but these are progressive diseases and the danger is that these people could very quickly become not able to work and indeed very ill. It is on this point that I would welcome some clarification.
