Leaked footage of the event, organised by a chapter of the Liberal Democratic Party, showed women in swimwear sitting on participants' laps, reports said. The event was "highly inappropriate and most regrettable", said Mr Kishida when grilled by lawmakers on Friday. At least one of the event organisers has since resigned from the party. The women, who are reportedly part of the Osaka and Kyoto-based Glamor Dancers troupe, were asked to use their mouths to receive banknotes hanging from participants' mouths, claimed local media reports.
