A former aide to the Duke of Edinburgh has been accused of sexually abusing a girl in the early 1970s.
Benjamin Herman, 79, is charged with three indecent assaults against the youngster, who was aged around 12 at the time, between 1972 and 1974.
During this time Herman served as the Philip's equerry, or personal assistant.
A spokesman for the Crown Prosecution Service said: "Benjamin Herman, 79, will appear at Wimbledon Magistrates Court on Monday. He is charged with three counts of indecent assault between 1972 and 1974 on a girl aged around 12."
A spokesman for Buckingham Palace declined to comment.
The Lieutenant-Colonel was Philip's equerry between 1971 to 1974, attending to his engagements and private matters, before he went on to become head of the Princess Royal's household in 1974.
Scotland Yard detectives are believed to have looked at the Duke's diaries during the period when the alleged offences took place, the Daily Mirror said, while statements have also been taken from former Buckingham Palace staff.
A spokesman for the Metropolitan Police would not comment on whether former palace staff had been interviewed.
He said: "Officers from Wandsworth CID investigating an allegation of historical sexual assault which occurred between 1972 and 1974 at a location in Putney arrested a 79-year-old man.
"He was subsequently bailed to a date in mid-June pending further investigation."
