Victims and survivors of domestic abuse and sexual violence are being let down by 'inconsistent, complex and short term' services in Wales, according to a new report.
The Wales Audit Office also found there is a gap in data about which victims and perpetrators are using public services, and what services are available.
It is calling on local authorities to review their approach to regional working to better integrate services and review their commissioning arrangements to remove duplication and overlap.
Auditor General Adrian Crompton said: 'It’s concerning to find that, four years after the introduction of this ground-breaking legislation, victims and survivors of domestic abuse and sexual violence are still being let down by an inconsistent and complex system.
'Effective collaboration and joint working are essential to ensure these services are efficient and effective, particularly given the fragmented nature of delivery across public bodies.'
