The chair of the education select committee is calling for agencies supporting children in care to improve joint working to better meet their mental health needs.
In an interview with Children and Young People Now ahead of the launch of the committee's inquiry into the mental health and wellbeing of looked-after children, Neil Carmichael said the lack of a proper joined-up health and social care support system for young people will be a key focus.
"If agencies are always isolated and not working with their fellow agencies then services get worse and young people can fall through the various stalls."
The committee has already held private evidence sessions with looked-after young people and care leavers, at which they were told about the inconsistent nature of support and the "cliff edge" in support when young people with mental health problems transition from CAMHS to adult mental health services at 18.
"They were not having appropriate assessments made at the start. How people are assessed and diagnosed will be at the heart of this inquiry."
The committee is expected to hold three evidence sessions between now and February with a report on its findings published in the spring. The first session took place yesterday - click here to watch
