DM-5 Response Accepted Self-assessed

Separate SIO and Family Liaison Officer roles

Recommendation

The Metropolitan Police should ensure that the role of the Family Liaison Officer is never carried out by the Senior Investigating Officer of an investigation. There is an inherent conflict between these two roles.

Published Evidence Summary
The following publicly available evidence relates to this recommendation:
According to the June 2023 Official government response and the Metropolitan Police Service / College of Policing's November 2021 publication, the Metropolitan Police Service (MPS) has ensured the separation of the Senior Investigating Officer (SIO) and Family Liaison Officer (FLO) roles. The National Major Crime Investigation Manual (MCIM), published in November 2021, clearly sets out guidance that these roles are distinct and have their own individual strategies. While the MCIM addresses the role separation, subsequent cases, such as that of Stephen Port, highlighted limitations in MPS FLO training, leading to HMICFRS recommendations for improved screening of FLO candidates.

The new National Major Crime Investigation Manual (MCIM) published in November 2021 covers all aspects of major crime investigation and sets the standard for all forces alongside the relevant Authorised Professional Practice (APP) produced by the College of Policing. The MCIM now clearly sets out guidance that the role of Senior Investigating Officer and Family Liaison Officer are distinct with their own individual strategies. Although recent cases, such as that of Stephen Port, recently demonstrated limitations in training for MPS FLOs. We expect the MPS to ensure that all future FLO candidates, and those currently in the role, are appropriately screened as HMICFRS recently recommended.

The MCIM (November 2021) clearly sets out that SIO and FLO roles are distinct with separate strategies. However, the Stephen Port case subsequently demonstrated limitations in MPS FLO training, and HMICFRS recommended improved screening of FLO candidates.

Role separation implemented through the MCIM but subsequent cases revealed ongoing FLO training deficiencies.
