Well-placed palace sources tell New Idea tensions are high after Harry, 33, confronted his stepmother Camilla with a string of accusations.
It's believed the 70-year-old's 'constant meddling' has forced Harry and Meghan, 36, to postpone their engagement announcement until the end of the year. Camilla has also been accused of forcing at least 14 key staff members to resign from Buckingham Palace, which has thrown wedding preparations into disarray.
The scandals have forced Harry to tell Camilla to back off, demanding she end her attempts to sabotage their nuptials.
'Harry is simply not going to put up with Camilla treating his bride or his relationship with anything other than respect,' says the palace insider. 'All Harry wants to do is get on with married life with Meghan, but all these obstacles keep on popping up and he feels Camilla is to blame.'
'The place is in turmoil and the mood is getting steadily worse,' a source tells The Sun.
Palace sources tell New Idea all fingers of blame are being pointed at Camilla, who 'uses the staff 24/7' and doesn't care about throwing Wills, Kate and, of course, Harry's plans to the side.
As a result of Camilla's sabotage, the Queen reportedly met with Harry and Meghan last week - asking them to look at wedding dates in early 2018.
Wedding plans have also been stalled thanks to thanks to Meghan's sister Samantha. The 52-year-old is writing a book about her royal bride-to-be sibling, which has caused nervousness among the senior royals.
'No one wants any skeletons coming out of Meghan's closet so close to a wedding announcement,' says the source. 'The Queen is very nervous.'
However, last week Samantha told UK TV show Good Morning Britain that her book wouldn't be a nasty tell-all, insisting Meghan will be amazing addition to the royal family.
'It's true I'm writing a book, but it's not a tell-all - rather it's about the beautiful nuances of our family home,' she revealed.
