"As time goes on, more and more people will be cared for in nursing homes" says Peter Tyndall, the Public Services Ombudsman for Wales.
"We need to make sure that what happened in England - where the quality of care in homes wasn't being properly monitored - isn't repeated in Wales".
"I know that the NHS in Wales are taking this seriously, but this is an issue that has to be dealt with across Wales, not just in this particular care home".
