Prince Philip was against it on the basis it would be traumatising, but ultimately the boys agreed on the basis that their grandad Prince Philip walked with them as he was a huge support to ehm in those difficult early days in Balmoral.
I agree, lemonpepperlady.
There's so much rubbish talked on here (and elsewhere) about PP by people who just saw a crusty old upper-class gent and projected their prejudices on to him.
Don't want to derail the thread (and it would be an essay!) but, the charge that he was a crude racist I don't think is fair. Of course, his views and his mode of expression might not be suitable for the 21st century, but I've read a lot about him and I don't think he was a racist. From what I understand, he respected particularly tribal people and thought the developed world were the crazy ones.
One eg: for some reason (I can't remember quite how this started) he was seen as a god by a Pacific island people and they sent him a ceremonial spear - a great honour. Philip didn't mock them, but instead had a special photo taken, showing himself throwing the spear and sent it to them with his sincere thanks. I know this sounds ridiculous, and I'm sure he didn't think he was a god, but his attitude was one of humility and respect towards them.
Yes, he cracked some regrettable jokes but I don't buy the fact that he was a nasty racist - that's a very crude interpretation of a complex man.
