David Burton has taken the first step in making defibrillators more accessible.

His father, Ken Burton, went to an emergency GP appointment - where he was told he needed an ambulance.

But 999 operators said it would be several hours before paramedics got to him.

The 82-year-old died hours later while his son David was driving him to hospital.

Now his family are taking action to help others.
