Even though Madrid is not going to be host to the 2012 Olympics, I think Her Majesty did a great work to support Madrid's candidacy.
I really liked that she closed Her speech with phrases in several languages. I watched the video of Her presentation, I had never heard Her speakign other language than Spanish and all I can say is that She speaks English and French perfectly, I can't tell that of her German and Greek because I can't speak those languages
Other thing I'd like to add is that the Queen has looked fantastic during these days in Singapore, I think she never looked so good before! She has chosen the most perfect outfits, fit for a Queen...
