Britain's Adam Peaty broke the 50m breaststroke world record in the semi-finals at the European Championships.
The 19-year-old, who has already won two golds in Berlin, won his semi-final in a time of 26.62 seconds.
"I feel absolutely amazing. I looked at the scoreboard about five times before I knew I had broken it," he said.
Peaty made his senior team debut at last month's Commonwealth Games in Glasgow, where he won two golds and a silver for England.
