My Lords, it is not the case that PIP is more generous than DLA. The Minister has only to consult the information produced by Motability on the number of the people losing cars to know that that is not a correct statement. Let me go back to the substance: we all know that DLA, followed by PIP, is not an income-replacement benefit but an extra-costs benefit associated with disability? What analysis have the Government made of the extra costs facing people with mental health problems, which would underpin their eligibility for the points assessment in assessing the awards for PIP? Given that there is not a clear answer, which I accept, would it not be wise and prudent to refer it to the Social Security Advisory Committee, whose job is precisely to steer the Government in areas such as this?
