The Duke of Edinburgh hit the headlines early in 2019 when he miraculously escaped serious injury in a car crash involving a mother and a baby.
The 97-year-old had been quietly enjoying his retirement before becoming embroiled in the road accident, and ensuing PR disaster.
The duke’s car flipped over and he was trapped, and had to be rescued through the sunroof by a passing motorist.
Philip, who was driving without a protection officer, was left “very shocked and shaken”.
He reportedly said “I’m such a fool” as he was pulled from the wrecked car by witness Roy Warne.
The other vehicle, a Kia, was carrying a nine-month old baby boy, his mother who was driving, and another woman, Emma Fairweather.
The baby was unhurt, but both women had to be treated in hospital, and passenger Ms Fairweather, who broke her wrist, called for Philip to be prosecuted if found to be at fault.
She described her upset that no-one from the royal family had contacted her to offer an apology.
Shortly before her newspaper interview was made public, a lady-in-waiting for the Queen called and left a voicemail.
The duke was given a precautionary check-up in hospital the day after the crash, and was said to have “no injuries of concern”.
Criticism was levelled at Philip for driving at the age of 97.
But AA president Edmund King said GP and family advice was more significant than a person’s age when it came to how long someone should keep driving.
The duke’s brand-new replacement Land Rover was delivered to the Sandringham estate just hours after the incident.
He was then seen driving without a seatbelt 48 hours after the crash.
Police spoke to the duke about the legal requirement to wear a belt and he also underwent an eyesight test, which he passed.
Author Gyles Brandreth wrote for The Oldie magazine at the time: “What the pictures of the prince back behind the wheel … show is that he wants to live the rest of his life his way and is determined to do just that.”
The duke eventually got in touch with those involved in the accident in the days that followed, writing in a letter to Ms Fairweather: “I would like you to know how very sorry I am for my part in the accident at the Babingley crossroads.”
He added of her broken arm: “I am deeply sorry about this injury.
“I wish you a speedy recovery from a very distressing experience.”
“After careful consideration, the Duke of Edinburgh has taken the decision to voluntarily surrender his driving licence,” the Palace said.
Norfolk Police confirmed a file on the investigation into the crash had been passed to the Crown Prosecution Service (CPS), which, five days later, announced that Philip would face no further action.
Chris Long, chief crown prosecutor for CPS East of England, said the level of culpability, the duke’s age and his surrender of his driving licence had been taken into account, and it had been decided it was not in the public interest to prosecute.
