Tokyo governor Yuriko Koike hit back on Friday at a candidate to be London mayor who offered to host this year's Olympics due to the coronavirus epidemic affecting Japan.
Shaun Bailey had tweeted: "London can host the Olympics in 2020. We have the infrastructure and the experience. And due to the coronavirus outbreak, the world might need us to step up."
"In the unlikely event that it be required, London, as it has done throughout history, will do its best to step up to the plate."
