"The severe conditions criteria in the bill exactly reflects how the functional tests are applied at present. That is in guidance. It’s being moved in this bill into legislation. It does take account of Parkinson’s. It does take account of MS. Because people need to meet the descriptors reliably, safely, repeatedly and in a reasonable time frame. And so I can give a very firm assurance to those who are concerned about how the severe conditions criteria will work for those on fluctuating conditions.
"The word constantly here refers, as I said in my intervention earlier, to the functional criteria needing to apply at all times, not to somebody’s symptoms."
