No one was charged at the time, though the police in Norfolk said on Saturday that the results of their investigation were pending. “The investigation file for the collision has been passed to the Crown Prosecution Service for their consideration,” the police said in a statement.

Both drivers tested negative for alcohol use at the time, the police said.

The Norfolk police confirmed that Philip had handed over his license to their office and, following standard protocol, they had forwarded it to the Driver and Vehicle Licensing Agency.

Days after the crash, Philip sent a letter of apology to the driver of the other vehicle, a copy of which was published by The Sunday Mirror.

“I would like you to know how very sorry I am for my part in the accident at the Babingley crossroads,” Philip wrote. He explained what had happened from his perspective, saying that bright sunlight shining on the main road had impeded his view.

“In normal conditions I would have no difficulty in seeing traffic coming from the Dersingham direction,” he wrote. “But I can only imagine that I failed to see the car coming, and I am very contrite about the consequences.”
