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.
PR is the bedrock on which our government is built. It's right at the heart of the way it operates. We have never had a more media-savvy government or PR-aware leadership. So why did they think they could spin their way around the Personal Independence Payment (PIP) disability cuts? To understand why they truly believed that the great British people would swallow the proposed PIP cuts you need to go back in time. Quite a long way.
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.
Jodie is 31 and lives in London, last October she was given the devastating news that she had breast cancer. A few weeks later she was told it had spread to her bones. She had to give up work almost immediately and suddenly found herself with barely enough money to live on. Jodie was advised by her nurse to apply for the Personal Independence Payment, the UK's main disability benefit, which would offer her some financial support. She applied in November, but seven months on and she is still waiting to find out if she is eligible. She is now at crisis point, struggling to pay for day-to-day expenses such as food and bills. This is unacceptable.
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. However those whose award runs out before that date or whose circumstances change will still be called in, potentially piling delay upon delay.
DWP Ministers once more find themselves making a virtue out of a necessity as they announced on Saturday that the roll out of Personal Independence Payment would be slower than planned.
