Part of King's speech
"Over the years we have had several occasions to meet with Your Royal Highnesses and the Royal Family. Each time we have been warmly received, and, perhaps needless to say, we have many dear memories from our stays. The most recent one was when Queen Silvia visited You at Highgrove on a very spontaneous stopover at the end of last year. I know that You then talked about coming here today."
here is the close ties
I was once in a luxury hotel in Scotland and they had pictures on the wall of the Swedish regent Couple and Prince Charles, including a thank you-note of the Swedish king and queen, where they thanked for their wonderful holidays for some years in a row and the marvellous hospitality and service they received when they hosted Charles there during their holiday. That surely was more than 15 years ago.... So it is a long-standing friendship and I bet Silvia knows a lot of Camilla's past woes...
