I support the crucial points that my right hon. Friend is making, but has he noted that the impact assessment on the proposed changes to DLA makes no mention of the impact on carers? There clearly will be a consequential impact on carers, depending on what benefits the people for whom they care receive and which rates of the daily living component or the mobility component will entitle carers to claim carers allowances. There is no mention of that whatever. Is my right hon. Friend aware of whether the Government have even made an estimate of the number of carers affected, and if so, why it has not been published?
