Princess Diana's biographer Andrew Morton suggests Thomas Markle is trying to heal the rift with his estranged daughter Meghan.
Speaking on Yahoo UK's 'The Royal Box,' Morton says: "Thomas Markle has been very quiet recently.
"He’d been approached by Italian, French and German and other TV channels to talk about his relationship with Meghan, or non-relationship, and he turned them down."
PR expert Nick Ede says: "I think Thomas of all them is going to be the one who actually wants to build this bridge and heal that rift.
"I think Samantha, on the other hand, is very much about headlines, financial gain, so I don’t think she’s going to go quiet, but I do think Thomas will definitely."
Historian Kate Williams adds: "I think you also have to accept the fact that we may not be completely privy to everything that is going on.
"We do not know what kind of conversations may or may not have taken place.
"Absolutely there is this sense that her father has been a loose cannon in the media, around the time of the marriage. In the last few weeks he has been notably absent from the air waves.
"He did, I think, an appropriate statement on the birth, so I think we have to kind of give them the benefit of the doubt for that."
