Since his death in August 2019, it has been a long three-year battle for justice for the family of Harry Dunn.
His parents, friends and family have campaigned tirelessly for their day in court - a campaign which came to fruition at the Old Bailey on Thursday when Anne Sacoolas, 45, pleaded guilty to causing his death by careless driving.
Sacoolas, the wife of a US diplomat at RAF Croughton in Northamptonshire, had originally been charged with causing death by dangerous driving, which she had denied.
The resolution brings to an end a long campaign for justice for Mr Dunn's family.
In three years the case has been championed by multiple foreign secretaries, two prime ministers and two presidents of the United States.
