As ever, H and reality remain parallel lines.
H has not quite grasped his diminished circumstances. Firstly, the whole world knows that KC3 is not talking to H and has cancer. Secondly, for those who matter, future KW5 is who matters. Future KW5 is the one meeting with Trump, Macron, Starmer, Merz, etc. And future KW5 has made his stance on his wayward brother quite clear...H is out.
The Sentebale temper tantrum proves that H is his very worst enemy, as H will alienate the blue-chip donor class that H desperately needs. Even worse for his ongoing charitable activities, by needlessly antagonizing the Charity Commission he has invited further scrutiny and harsher sanctions for the rest of his UK activities...as the Commission may choose severity over leniency in matters where they have discretion.
