Speaking of Her Majesty's Sandringham estate, Burrell claimed to the US tabloid that it will feel like a "parallel universe" to Meghan.
“That house is occupied by some of the biggest personalities and egos in the country,” said Burrell.
“Everyone is jostling for position and attention, and they’re bouncing off the walls after four days. It’s like a pinball machine.
“No one could prepare her for it, not even on a film set, but this is the real world.
“Sandringham is ‘Downton Abbey’ on speed. It’s so detached from our world.”
A royal insider confirmed to the National Enquirer: “Everybody thought Di was paranoid, and look what happened to her.
“It’s always a risk to go to war against the palace, but Paul is brave by speaking out, in part to protect himself, but mostly for Meghan. He wants her to be safe and be vigilant of the enemies around her.
“She and Harry have been married for seven months, but some of the staff don’t think they’ll last a year.”
Meanwhile, Meghan will be forced to fend for herself into the new year after her mum, Doria Ragland, was snubbed from visiting the palace over Christmas.
“Meg’s furious! She feels trapped and constantly exhausted,” a snitch explained. “She needs all the help she can get, but it’s clear the royals are setting her up to fail.”
The Royal Family are yet to respond to Paul Burrell's newest claims.
