And for more on today's Torch Lighting Ceremony, we're now joined by Dan Williams, who's on site in Olympia.

Q1. Hi Dan. Obviously the organizers don't want any unexpected complications, such as rain dousing the flame, so what's the weather like at the moment?

Q2. Your report mentioned that the Torch Relay will pass through a refugee camp. This has become an important theme for the Olympics, hasn't it?

Q3. Now the build-up to these Games has been hit by a number of controversies, so is there anything today's ceremony will do to help change the perception of Rio 2016?
