The president of the Commonwealth Games Federation says organisers of this year's Games in India repeatedly ignored warnings that their preparations were slipping behind schedule.
Mike Fennell says there is still work to be done to ensure the XIX Commonwealth Games go smoothly.
In an interview with the BBC, Mr Fennell said that while there was no shortage of enthusiasm from Delhi's organisers, there was frustration at the chaotic way Indian officials had planned for the Games.
Repeated warnings were not heeded, he said, leaving Delhi with too much to do and not enough time to do it.
Rejecting suggestions that the Commonwealth Games Federation could have done more to prevent the delays, he insisted that taking the event to India was still the right decision.
But with the Games beginning on Sunday (local time), workers at the Games Village and the main venues are still racing to finish everything in time for the Opening Ceremony.
Several teams had suggested that the standard of accommodation provided might cause the Delhi Games to be cancelled or postponed.
The collapse of a footbridge close to the main stadium and of the weightlifting venue roof increased concerns over construction standards.
