It is acknowledged in Mr Duncan Smith's resignation letter that the changes to Personal Independence Payment system are defensible in narrow terms. That is hardly a surprise as he had agreed them and anyway, whether the changes in criteria were the right ones, clearly something had gone wrong with a scheme that had moved so far from its target.
Charities have rightly been arguing against specific benefit cuts on behalf of their members and their beneficiaries; drawing evidence from disabled people, carers and also from their own professional staff; and making the case for excluding some of the most vulnerable and poorest members of society from further cuts to their limited income.
David Cameron has spoken of his belief in a 'compassionate nation' - one that protects the most vulnerable. If his Government is serious about this, they need to make sure that they protect all disability benefits and housing benefit for younger disabled people. Only then will people on the autism spectrum receive the support they need to live independent and fulfilling lives.

PIP has been available to new claimants since June 2013. Most of those who are currently on DLA will not go through the reassessment process until October 2015.

As thousands of women counted down the days and hours to discover the official line on the potential ticking time-bombs sitting within their bodies, arguments raged over whether it was fair the tax payer foot the bill for the removal of the PIP implants and in amongst it all we appeared to gloss over the more important issue at hand: why so many thousands of women, year after year, feel compelled to have surgery in the first place.
