Prince Harry and Meghan Markle have revealed what they claim was said in a fateful phone call between them and the Queen just before Megxit.
The couple allege they were blocked from seeing Her Majesty, despite her inviting them to come and stay with her.
It's one of several new revelations the couple make about the royal family in the latest episodes of Netflix's wildly popular Harry & Meghan documentary series.
In episode five, The Duke and Duchess of Sussex claim they were blocked from seeing the Queen after Harry had told his father - then Prince Charles - of his intentions to step down from royal duties just before returning to the UK from Canada.
"Before we left I spoke to my grandmother as well and told her that we were coming back... and I would love to come and see you... she told me that she had no plans for the week," said Harry.
"She said: 'Well, why don't you come up? You can have tea. Why don't you stay the night, you and Meghan?'"
Meghan added: "So we were flying back from Vancouver straight to Heathrow and right as we were getting on the plane, this urgent, urgent message comes through to [Harry] saying: 'You are not allowed to go and see Her Majesty, make sure your principal is aware you cannot go and see her. She's busy, she has plans all week'."
"I was like, 'Well, that's certainly the opposite to what she had told me'," said Harry.
"Once we were back in the UK, I rang her and said: 'I'm now told that you're busy'. She goes: 'Yes, I didn't know I was busy. I've been told that I'm busy. I've actually been told that I'm busy all week'. I was like 'wow'."
Meghan added: "I remember looking at [Harry and thinking] my gosh, this is when a family and a family business are in direct conflict. Because they're blocking you from seeing the Queen, but really what they're doing is blocking a grandson from seeing his grandmother."
The final episodes - four, five and six - were released on Thursday evening.
Netflix said the first three episodes, released last week, recorded 81.55 million viewing hours globally in its first week - more than any documentary it has released ever before in premiere week.
Buckingham Palace and Kensington Palace declined to comment on the allegations in advance.
