Canada has become the first nation to officially withdraw its athletes from the 2020 Olympic games, sparking further doubt over whether the Tokyo games will go ahead as planned.
The Canadian Olympic and Paralympic committee said it had taken "the difficult decision" to withdraw after consulting athletes, sports groups, and the Canadian government.
It comes after the International Olympic Committee gave itself a four week deadline to make a decision on whether or not to postpone the games, which are due to begin in July.
The board have insisted that cancelling the games is not on the agenda.
However postponement is thought to be the most likely outcome.
