Ambulances delays reach 40,000 hours in Wales
Patients could be at risk because there has been a five-fold increase in delays faced by ambulance crews outside hospitals, according to the Welsh Ambulance Service.
It has told AMs that almost 40,000 hours were "lost" in 2014 because of so-called "handover delays".
Its report indicates that is up from around 8,000 hours lost in 2008.
Any wait longer than 15 minutes to transfer patients into hospital is logged as a handover delay.
