Wales NHS: Complaints to ombudsman more than triple
Complaints about the NHS in Wales have more than tripled in six years, BBC Wales has learned.
Public services ombudsman Peter Tyndall says part of the rise is over the quality of care and warns services will become less safe without change.
Complaints have increased from 191 in 2006/7, when his office was created, to an estimated 680 for 2012/3.
The figures have been revealed amid controversy over a major NHS shake-up.
