Japan’s Tokyo 2020 boss has cast fresh doubt on the Olympic Games scheduled for next year.
Tokyo 2020 president Yoshiro Mori says the Olympic Games, already postponed to 2021, would be "scrapped" if they could not take place next year.

The International Olympic Committee and the Japanese government last month postponed the Games until July 2021 because of the impact of the coronavirus outbreak.
With the epidemic's worldwide infection rate climbing and experts suggesting a vaccine is still a long way off, questions are being asked about whether the huge setpiece event might need to be delayed further.
"No. In that case, the Olympics will be scrapped," Mori said in the interview with Japanese sports daily Nikkan Sports, when asked if the Games could be postponed again until 2022.
Japan Medical Association chief (JMA) Yoshitake Yokokura told a media briefing on Tuesday it would be a big call for the Games to go ahead without a vaccine.
"I am not saying that Japan should or shouldn't host the Olympics, but that it would be difficult to do so," he said. "Unless an effective vaccine is developed, I expect hosting the Olympics will be difficult."
Regardless, former prime minister Mori remained confident the they would go ahead in 2021.
"We have delayed the Olympics until next summer after we will have won the battle," he was quoted as saying.
"The Olympics would be much more valuable than any Olympics in the past if we could go ahead with it after winning this battle. We have to believe this otherwise our hard work and efforts will not be rewarded."
Olympics and Paralympics ceremonies could be combined
Asked about Mori's comments, Tokyo 2020 spokesman Masa Takaya emphasised organisers were focusing on next year.
"New dates for the Tokyo 2020 Games have been set and our mission is to deliver the Games next year," he told a news briefing.
Mori "mentioned this comment in his own thoughts," Takaya added.
During the interview, Mori also suggested the Olympics and Paralympics might share opening and closing ceremonies instead of holding their usual separate ones.
Mori said this would cut costs, though the idea is further complicated by tickets already being sold for all four ceremonies.
"It's a big hurdle," he admitted.
"But due to the impact of coronavirus, the situation next year will be completely different ... we have to review key areas, including the ceremonies."
