Aaron Moores has taken the silver medal in the men's S14 100m backstroke, after a good turn put him up to second from third place.
Marc Evers of the Netherlands dominated the final and won the gold with a world record time of 1:01.85 compared to Moores's 1:04.44.
Au Kai Lun of Hong Kong was just edged into third place with his 1:04.53, just shy of Moores.
Ben Proctor, GB's second medal hopeful in the race, could only manage fifth.
