The Met may be failing to identify serial killers because it is not properly investigating unexpected deaths, the police watchdog says.

It identified five key failings at the Metropolitan Police in a report: a lack of training, poor supervision, "unacceptable" record-keeping, confusing policies and "inadequate" intelligence procedures.

Today’s Mishal Husain spoke with Matt Parr, HM Inspector of the Constabulary, about the report.

Mishal also spoke to Donna Taylor, the sister of Jack Taylor who was the last victim of Stephen Port, about her experiences dealing with the police following her brother’s death. Finally, Mishal talked to Assistant Commissioner of the Met Police, Louisa Rolfe, regarding the dangers of poor police practices allowing history to ‘repeat itself’.
