Prince Philip's former shipmate has quipped that the royal was "a bit randy" when he served in the Navy in the 1940s.
Commander Keith Evans made the joke when they were reunited at the Pangbourne College in Berkshire, Reading on Tuesday (09.05.17) - where Evans was a pupil - and while at first he didn't think he'd ought to have his joke published, he decided to let it out.
According to The Sun newspaper, Evans said: "He was a bit randy but you had better not put that down."
He also joked that now the 95-year-old royal - who married Queen Elizabeth in November 1947 - is stepping down from his duties later this year, he'll have the freedom to do whatever he likes rather than obey orders from his 91-year-old wife.
He laughed: "Like Prince Philip, I'm standing down from most things from August.
"I think it is rather good news. He will do what he wants rather than what she tells him to do."
The Duke of Edinburgh was full of jokes when he announced his retirement last week.
Making light of the news, he quipped that he is standing down because he can no longer stand up.
A guest at St James's Palace said: "I'm sorry to hear you are standing down."
And Philip, who is known for his witty remarks, is believed to have replied: "Well, I can't stand up much longer."
Although Philip will not accept any new invites or visitation requests during the latter part of the year, he will remain committed to the engagements he has lined up from now until that period, and could attend "certain public events from time to time" if he chooses to.
The official announcement regarding the Royal Knight of the Garter states: "His Royal Highness The Duke of Edinburgh has decided that he will no longer carry out public engagements from the autumn of this year. In taking this decision.
"Prince Philip will attend previously scheduled engagements between now and August, both individually and accompanying The Queen. Thereafter, The Duke will not be accepting new invitations for visits and engagements.
"Although he may still choose to attend certain public events from time to time."
