The Crown Prosecution Service said it wouldn't be in the public interest to punish the 97-year-old.
The Crown Prosecution Service has declared that Prince Philip won't face punishment for his involvement in a crash last month that left two people injured.
The CPS said that it would not be in the public interest to prosecute the 97-year-old, who surrendered his driving license last week.
"We took into account all of the circumstances in this case, including the level of culpability, the age of the driver and the surrender of the driving license," Chris Long, Chief Crown Prosecutor from CPS East of England was quoted by the BBC.
He gave up his driving license on Saturday despite being seen behind the wheel mere days after the crash.
"After careful consideration, the Duke of Edinburgh has taken the decision to voluntarily surrender his driving licence," a Buckingham Palace statement said.
Initial reports suggested that Prince Philip hadn't apologized to the victims of the crash, but he was later revealed to have written to one of them – Emma Fairweather, who suffered a broken wrist in the incident.
In the letter, Prince Philip admitted that he was "deeply sorry" for the incident, and wished Ms Fairweather "speedy recovery from a very distressing experience".
"I would like you to know how very sorry I am for my part in the accident at the Babingley cross-roads," Prince Philip said in the letter.
The letter was signed off "Yours sincerely, Philip."
Responding to the letter, Ms. Fairwaether called it a "nice touch," adding: "It is a difficult letter to write – to know what would be the right thing to say without making me more upset."
The crash on Thursday, January 17 occurred on the on the A149. The Royal was uninjured in the incident, but he was checked over by a doctor before returning to Sandringham.
