Delay: Paul Nelson died after an ambulance took two hours to reach his Norfolk home
Paul Nelson, 26, collapsed in his bathroom in the village of Blakeney in Norfolk, after returning from a shift at a local hotel with a headache.
Mr Nelson's parents watched as his condition deteriorated, culminating in him coughing up blood and collapsing on the bathroom floor.
His father Sidney Nelson, 59, and stepmother Haylie Wardhaugh, 45, dialled 999 at 11.15pm but an ambulance did not arrive until after 1am the next day - taking more than six times longer than targets dictate.
