Prince Philip warned Harry against marrying Meghan Markle , telling him 'one steps out with actresses, one doesn't marry them', it is claimed.
The Duke of Sussex is known to have a close bond with his grandfather and he was one of the first people to meet the royal couple's son, Archie, after his birth in May.
The 98-year-old also attended Harry and Meghan's wedding in May last year amid speculation he would miss the big day while recovering from a hip replacement operation.
The Sun has now reported claims that the outspoken prince warned his grandson against marrying the former Suits actress.
The newspaper added that an insider previously said Harry, 34, stood up for Meghan in response to concerns about her.
The Duke of Edinburgh has offered relationship advice in the past, notably in 1997 when he claimed that the key to a successful marriage was tolerance, according to the Sunday Times Magazine.
He reportedly said: "Tolerance is the one essential ingredient. You can take it from me that the Queen has the quality of tolerance in abundance."
Royal expert Katie Nicholl previously claimed that a feud developed between Harry and his brother Prince William over his relationship with Meghan.
Speaking in a TLC documentary on the royals, she said: "William was quite concerned that the relationship had moved so quickly.
“And being close to Harry, you know, probably the only person close enough to say to Harry ‘this seems to be moving quickly, are you sure?’ And I think what was meant as well-intended brotherly advice just riled Harry.”
Buckingham Palace declined to comment on Philip's alleged statement about Meghan, according to The Sun.
