A series of reviews into the deaths of 12 children known to state services has found that a lack of access to mental health was a "strong theme" in many of the cases.
The independent National Review panel says three out of four young women who died by suicide since 2010 had been on long waiting lists for mental health services - with one unable to access help in the days before her death.
The independent review group says a multi-agency mental health service is needed if children are to get the care they need.
