There are conflicting stories in Harry's and Omid's books:
Archie was born at 05:26.
In Spare, Harry says:
I don't remember phoning anyone, texting them. I remember watching the nurses run tests on my hour-old son, and then we were out of there. Into the lift, into the underground car park, into the people-carrier, and gone. Within two hours of our son being born we were back at Frogmore. The sun had risen and we were behind closed doors before the official announcement was released …
Saying Meg had gone into labour?
I had a tiff with Sara about that. You know she 's not in labour any more, I said.
She explained that the press must be given the dramatic, suspenseful story they demanded.
But it's not true, I said.
Ah, truth didn't matter. Keeping people tuned to the show, that was the thing.
In Finding Freedom, Scobie says:
Harry took to texting and calling friends ... and family ... Lastly, Harry had Palace aides to inform, including Sara, which he did at 9:30 a.m., just as they were leaving to return to Frogmore Cottage.
So, were they back at home within 2 hours or 4+ hours?
