Families are unable to say goodbye to loved ones because of changes to death certificates which has also led to overcrowded mortuaries, a funeral director has said.
Geraint Griffith said it was taking between 10 and 20 days for bodies to arrive due to the new system, introduced in September, which he said made it hard to make them look presentable for loved ones.
Overcrowding has also led to hundreds of bodies being moved to other mortuaries in the past six months, and Mr Griffith said families were not being informed.
The lead medical examiner for Wales said he was working "tirelessly" to address any delays.
