No I think you have misunderstood the nature of his celebrity - Harry will be very popular amongst young folks , a bit of a rock star - with no dount heartfelt charity work and a good PR company.
I don't think he'd appeal to young people either! He's not young - he's middle-aged, highly privileged, none-to-bright and frankly, I don't think the PR company has been set up that can turn around his image in the UK. M & H don't seem to be able to manage their PR in the US, do they? Apart from anything else - they can't seem to keep the staff.
And he's not even attractive - and I only say that reluctantly because I hate all this stuff about people's physical appearance, but in the real world he'd need to be to be a celebrity.
But if he's not a royal prince and doing 'princing', then what on earth is Harry's USP? Absolutely bleedin' nothing! He's not young, clever, talented or particularly handsome in celeb terms. Why would youngsters like him???🤔
