China's Pan Shiyun has won gold in the men's S7 50m butterfly with a surprising victory from lane two.
Pan's swim was the first ever sub-30s time in the event in the S7 category as he set a new world record of 29.49s.
Yevheniy Bohodayko took silver with a European record of 30.19, but in truth no other athlete was ever in the race.
Wang Jingang came through in third to take bronze with a time of 30.75s.
GB's Matthew Walker could only finish seventh in the race.
