 Thank you to Michael Williams. Well, very shortly, the Paris mayor, Anne Hidalgo, will be plunging into the River Seine to show how the cleanup has made it easy for the Olympic Games in less than 10 days. Her office announced last Friday that La Seine has been clean enough to swim in for most of the last 12 days. The river is due to be the venue of the opening ceremony and to host the triathlon and marathon swimming events.
