Waveney MP Peter Aldous says lengthy handover delays at hospitals is one of the main factors in causing ambulance response times to grow.Mr Aldous spent two evenings with crews from the Waveney depot recently.
He says another factor he discovered was the public calling out ambulances inappropriately when they should have simply been calling their doctors. An increase in demand due to the region's ageing population was another factor.
He has written to the East of England Ambulance Trust with his findings. He has asked for a meeting with the Trust to discuss the issues.
