Police who investigated the disappearance of Nicola Bulley from beside a riverbank have been heavily criticised in a damning report. Lancashire Police's decision to reveal the mother-of-two's mental health issues was condemned as "avoidable and unnecessary". The College of Policing's chief executive officer Andy Marsh said there was "substantial learning" for the Lancashire force. On the Sky News Daily, host Niall Paterson is joined by former chief constable of Northumbria Police Sue Sim, who was the top officer at the force when gunman Raoul Moat shot his ex-girlfriend and killed her new lover, before shooting a police officer. She explains the criticisms and the difficulties when dealing with high-profile cases. Plus, Martin Brunt, our crime correspondent, details what the report says about Lancashire Police's investigation.
