Garda Commissioner Nóirín O'Sullivan has highlighted her concerns about leadership gaps within An Garda Síochána.

The commissioner addressed the third public meeting of the Policing Authority this afternoon.

She said implementing the biggest reform programme in the Garda's 94-year history requires a cohesive and adequately resourced management structure.

Commissioner O'Sullivan said supervision at all ranks requires the appropriate amount of managers at all ranks and grades.

She added that otherwise supervisors, particularly at local level, become over burdened, which creates risks.

She said that while the ranks order of the force states there should be 390 inspectors, there are currently only 240.

She added that more needs to be done in order to ensure the necessary level of leadership, governance and management of the organisation.

Commissioner O'Sullivan said she wrote to the Secretary General of the Department of Justice this week requesting the immediate appointment of two Assistant Commissioners.

She has also requested that the appointment of eight Chief superintendents and 26 Superintendents selected from recent competitions be made as quickly as possible.

The commissioner said she has raised on several occasions with the Policing Authority the profound risks to continued effective delivery of policing and security services from the current leadership gaps in the organisation.
