Great Britain's Adam Peaty broke the World Swimming Championships record for the men's 100m breaststroke as he posted the fastest time in the semi-finals in Kazan this evening.
The Commonwealth and European champion raced to victory in a time of 58.18 in the second semi-final, beating the record that South Africa's Cameron van der Burgh had set in the first semi-final just a few minutes earlier.
Ross Murdoch came fourth in his race with a time of 59.75, which was good enough for seventh overall and a spot in tomorrow's final.
Peaty was just 0.2 seconds off his own world record, which he set in London in April.
