The International Olympic Committee has sent a clear warning to the organisers of the Rio 2016 Games that "every second counts" after visiting the Brazilian city.
With just over two years to go, the IOC said that a "constant, concerted and integrated effort is required for the successful delivery of the Games and its legacy".
It added: "Although progress is being made, each decision that is postponed and each subsequent delay will have a negative impact on delivery. Total focus and dedication are therefore required."
ITV News' Brazil correspondent Nick Ravenscroft, who was at the news conference, tweeted:
IOC presser re Rio 2016. Time + again say they have been "given assurances" that problems and delays in preparations will be resolved (1/2)
Scepticism from assembled hacks. These sound v much like assurances given re preparations for World Cup. And that's dangerously late. (2/2)
