Kettering Hospital's 43 errors in Victoria Harrison case

A hospital where a girl bled to death has revealed a catalogue of errors, weeks after withholding details for fear of "putting staff under more stress".
Victoria Harrison, 17, was found dead the day after an appendix operation at Kettering General Hospital in 2012.
An inquiry uncovered 43 errors, but bosses refused to release full details.
The BBC has now learned routine observations were discontinued and nurses' conduct was unprofessional.
