Prince Harry, Meghan Markle to visit Princess Diana before wedding

London, January 30 (IANS) Prince Harry and Meghan Markle will visit Princess Diana's grave before they get married later this year.   The 33-year-old royal is set to marry the American actress in May this year, but before they tie the knot, they are believed to planning one last trip to his mother's childhood home in Althorp, where she was buried, reports femalefirst.co.uk.   Harry and Meghan, 36, previously visited Althorp in November, where sources suggest Harry "quietly" asked his late mother for permission to pop the question to Meghan later that month.   A source told the Daily Star newspaper: "Harry has already taken Meghan to Althorp to see his mum, but they will go back before the big day. Harry wanted to take Meghan to see and speak to her ... it was very personal for Harry. I think he quietly asked his mum for her blessing to marry Meghan, too."   It comes after the flame-haired Prince admitted he believes the former "Suits" actress and his mother would have been "thick as thieves" if Diana were still alive to witness him tie the knot with the beauty.
