MELBOURNE (Reuters) - International Olympic Committee (IOC) vice president John Coates has called Brazil's preparations for the 2016 Rio Games "the worst" in his experience 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.
