TOKYO, July 24 (Reuters) - Tokyo 2020 organisers added to speculation that scandal-hit former chief Yoshiro Mori could return as an honorary adviser on Saturday when they stopped short of dismissing a report about his comeback. Moves are under way to name Mori an honorary supreme adviser of the organising committee, the Asahi newspaper said on Friday, quoting several sources. The appointment would likely renew global outrage after Mori was forced to resign over sexist comments early this year. "As for the positions of those who have contributed to the organisation of the Games, we will deal with them as necessary, but we can"t comment on any individual appointments," Tokyo 2020 spokesman Masa Takaya told a news conference when asked about the report. The octogenarian former prime minister, who has a long history of gaffes, stepped down after his comments that women talk too much sparked a storm of global criticism on social media. It was one of several scandals to plague organisers and put a sharp focus on social issues like gender equality in male-dominated Japan. Mori"s return could erode the goodwill earned by organisers with their choice of tennis superstar Naomi Osaka to light the Olympic cauldron on Friday. The selection of Osaka, the daughter of a Haitian man and a Japanese woman, reflects the changes and slowly growing diversity coming to a once ethnically homogeneous country.
