I also thought there would be specific examples leading to concluding paragraph.
The article is about a timeline of events, which is linked at the bottom, as well as many other links in the body of the article that lead to much more info and examples, I'm not sure what more they could have done.
As for your anecdote, I can second it, since I had a similar thing happen to me (moved to a new area, had my benefits stopped while they re-assessed me in the new area). This happens due to privatisation and a breaking up of the system so that each area is managed by a different contractor, and they don't really communicate (since none are designed to give the claimant the best outcome, so why would they). I knew my benefits had been stopped and it still took a little over a year to get everything going again (with significant support).
