Latest ambulance performance figures show an improvement on March but are still below the all-Wales targets for the eleventh successive month.
Statistics from the Welsh Government show an increase in emergency calls in April by over 6 per cent on the previous year.
However only 57.2% of ambulance crews were at the scene of 'immediately life-threatening' calls within 8 minutes - up almost 4% on the previous month of March - but still not meeting the government's target of 65%.
