In his latest outburst, he compared the Royal Family to being like Scientologists for their treatment of him.
But sources have revealed that the newly weds are 'not going to engage in war of words' with the outspoken 74-year-old.
Now people placed close to the Royal Family have told The Sunday Times newspaper that there is a strategy in place to deal with the former Hollywood lighting man.
"Meghan doesn't think it's a fair game between her father and the media so she's not going to engage in it or instruct anyone on her behalf to set the record straight," one source claimed. "There have always been fears over his vulnerability."
The insider added, "Now he's got himself into a cycle of talking publicly. It's very sad."
She is completely estranged from her dad, but still has a very close relationship with her mom Doria Ragland who is on the verge of moving to London.
However, she retains the full support of the Royal Family as she learns to cope with her new high profile life.
Another source close to Prince Charles revealed, "The prince will be very sympathetic towards Meghan and the difficult situation she is in.
"But I suspect the Queen will be rolling her eyes and thinking: crikey, what is going to become of all this?"
