It was the BBC, not ITV, and Panorama is a pretty reputable show from what I understand.
The flip side of all this is that they aren't all that bad. My son might well have died if I'd tried for a home birth. And while I had loads of horrid complications, I would say that overall, my care was very good and the complications weren't due to care. There were things that sucked, and one of the wards was closed due to staff shortages, but it could have been much, much worse.
Sadly, it is the luck of the draw in so many cases. I think big cities are probably the worst for overcrowding and under-staffing.
