It’s one of the biggest scandals in the history of the NHS - many babies died whilst others were left with life-changing injuries following repeated failures in maternity care at hospitals in Shropshire. Reporting for Panorama, the BBC's Michael Buchanan who first investigated the extent of this hidden tragedy meets families who have never spoken out before and former insiders who describe a dysfunctional culture that contributed to the truth being buried for so long. The programme also hears from the former midwife who is leading an official inquiry into what went wrong, ahead of her full findings being published next month.
