I do agree to extent it's a private party let them all let there hair down but Charles, William and Harry and their spouses are 'working' royals. I know they have their own money to but their whole lifestyle is heavily publicly subsidised (at least that's my understanding). I don't know who paid for what last night but even the venue Buckingham palace is being renovated with public money. I understand that is the price of having a monarchy but the flip side is they have to engage the public and give them what the want to extent as well ( dresses tiaras and heels in this case). Taking the royals weddings the evening doos were private I had no problem with that as we saw Kate/Meghan/Eugenie all dressed up on route. It didn't effect the privacy of the event and it kept people happy.
The state banquets are a bit different I k ow there are know posed pics of Kate Meghan ect but I think that's protocol as the queen Charles and camillia has one. But we do get full length pics it's enough. At the end of the day if they want a private life so badly they can always step out of the monarchy and live a normal life but they don't do they!
I do sympathies re the press o completely see why William is reluctant but in 2018 they can interact with the public without them. They take the pic they release it on social media, the public are happy and the press haven't been able to intrude. It just seems so simple to me.
And that's who someone pretty pro monarchy feels all for the want of some pictures
