I do feel very sorry for Prince Harry over what has happened at Sentabale - and indeed for his Lesotho co-founder.
It is clear that both sank their hearts in this project. That the whole board of trustees resigned at once, does suggest that something has gone badly wrong, which suggests something more than just a clash of personalities.
Hopefully, the Charity Commission enquiry will get to the heart of the matter and require changes that sort the problem out.
I have always thought it a shame that Prince Harry ever left the army. He was well liked and respected, which suggests he was doing a good job, which is, for example, more than be said of Prince Andrew, who was cordially disliked by almost everyone who served with him.
