From 2-4 years ago. I helped 3 people who had benefits stopped within a week for not returning questionnaire or attending medical. All had severe medical problems which made it hard for them completing paperwork or dealing with authority figures. Their payments were reinstated as soon as the form or medical was done. They were all fortunate to end up passing the medical - sure that would not happen now.
Thanks for the links. The first blog looked promising, but seems to degenerate to some very strong rants:
all employees of the DWP are narcissistic, sociopathic twats who have a serious god complex
I feel this is inaccurate (75% of staff yes, but not all

)
The guardian article, and some others, proves that ATOS are not in this to be fair and honest. Therefore, I must make sure to hold them to account in every way possible to protect my interests.
After my last medical, I tried to trace the doctor to complain to but ended up with 2 doctors with same name. ATOS refused to confirm which of the 2 examined me. GMC refused to accept complaint without specific doctor details.
This is how I got my idea to get doctor to fill in a form to confirm id,qualifications,specialisms,professional registration etc. These people are unlikely to understand common law or legal terms and conditions of contracts, but they should understand informed consent. Until I am informed that they are properly qualified and experienced to examine me, I can decline my consent.
