Teesside's coroner has resigned announcing his retirement for the end of April. In a statement Michael Sheffield said his retirement "follows the implementation and satisfactory process in the increased resourcing and administration of the Teesside coroner's office."
It follows a decade of criticism that some inquests on Teesside take too long to be heard. There is still a backlog of more than 300 inquests waiting to be heard at the moment, which the Chief Constable of Cleveland Police has vowed to reduce.
Last year an investigation concluded Mr Sheffield wasn't to blame for the backlog.
He is the longest serving coroner in England and Wales having served on Teesside for more than four decades.
The Senior Coroner for Teesside has announced his retirement. Michael Sheffield has worked with the service for more than four decades.
His retirement follows repeated calls for him to step down after it was found that the service had up to 300 families waiting for inquests at any one time. The backlog was reduced after reforms.
A panel investigating the coroner's service on Teesside has said that grieving families must be told how their loved ones died as quickly as possible.
Eighty per cent of inquests there take longer than the national average.
Up to three hundred families are being kept waiting at any one time.
The panel says the coroner, Michael Sheffield - and Cleveland Police - should recognise the failings, and act upon them.
