They call it the greatest show on Earth. With 11,000 athletes from 207 countries taking part in 306 events, the 2016 Rio Olympics did not disappoint in terms of size, delivering a mammoth festival of sport unrivalled by anything else on the planet. But with mammoth size comes mammoth challenge, namely the gigantic task of organising and running the show. Staging the greatest show on Earth demands one of the biggest logistical operations - and a truly global effort.
An official hospitality centre for African nations during the London 2012 Olympic games has been forced to close amid allegations that suppliers have unpaid invoices totalling hundreds of thousands of pounds.
The center, situated opposite the Royal Albert Hall, featured an exhibition area and restaurant open to the general public as well as reception area for games participants, sponsors and officials.
