According to official figures released today, the Welsh Ambulance Service has again failed to meet its response time targets.
In May, 54.1 per cent of ambulances reached life threatening incidents in eight minutes down from 56.7 per cent in April and below the target of 65 per cent.
The Welsh Conservatives are blaming a lack of investment from Labour ministers and a failure to address logjams at A&E departments.
The Leader of the Welsh Liberal Democrats, Kirsty Williams is labelling the figures as a "national disgrace".
Responding to today's figures the ambulance service response times which showed targets had been missed again for the most urgent 999 calls, the Welsh Government said:
The ambulance service has yet again missed its target for the most urgent 999 calls.
In March only 55% of ambulances reached the 8 minute target. 65 percent of ambulances are supposed to reach that goal.
The worse response times were in Blaenau Gwent followed by Rhondda Cynon Taff.
