Rome's Trevi Fountain provided the spectacular backdrop to the sight of G20 leaders throwing coins over their shoulders into the waters of the Baroque monument on Sunday morning. Held amid tight security, the photo-op resulted in street closures across the historic centre ahead of the second day of G20 talks -  centred on 'People, Planet, Prosperity' - at the futuristic Nuvola conference centre.

Italian prime minister Mario Draghi led the group, which did not include all of the G20 leaders, notably US president Joe Biden. The atmosphere was relaxed as the G20 heads each tossed a €1 coin, with outgoing German chancellor Angela Merkel rinsing her hands in the fountain's waters afterwards. The coins were minted specially for the occasion and feature Leonardo da Vinci's Vitruvian Man, the symbol of Italy's G20 Summit.
