There is no reason that he couldn't have confirmed accommodation when he gave his 28 day notice. But I think HAM were holding out for a better offer than BP - probably somewhere in the vicinity of the Wales family so that they could "accidently" bump into them on the Windsor estate. He spent all last week trashing the suitability of BP and rejecting it. It was pretty creepy on one of his previous trips that he chose a hotel close to the Wales kids' school 🤔
I think that when it became clear that BP was the only offer - he flounced, probably intending to get a hotel. But guess what... it's the summer, it's Wimbledon and there are likely few hotels with a whole floor available for HAM, the entourage and the security.
So he suddenly decides today to resurrect the "offer" with a few hours notice and Charles is p*ssed off with the HAMateur dramatics and says no ... and Harry runs straight to the press....
BP may also have got wind that Harry was lining up to do post court interviews from inside BP...
This has been a complete clusterfuck from HAM PR - there were many who said, when he was appointed, that hiring Liam's hard-nosed, aggressive PR was a bad move from HAM ... this has become very apparent.
