The International Olympic Committee (IOC) vice president John Coates has called Brazil's preparations for the 2016 Rio de Janeiro Games "the worst" he has ever seen and critically behind schedule, but warned there was no "plan B" to find another host.
Attending an Olympic forum in Sydney, Coates told delegates that construction had not commenced on some venues, infrastructure was significantly delayed and water quality was also a major concern two years out from the Games.
He described the situation as worse than Athens, referring to preparations for the 2004 Games, which were plagued by construction delays.
The first Games on the South American continent have been plagued by delays, rising costs and bad communication between different levels of the Brazilian government and organisers, prompting criticism from international sports federations.
