South Africa’s Cameron van der Burgh set a new world record for the men’s 50m breaststroke in the heats at the World Swimming Championships.

The defending champion’s time of 26.62 seconds eclipsed the 26.67 he set at the World Championships in 2009.

Britain’s Adam Peaty swam 26.62 last August, but that time is still to be ratified because of an error in the blood-testing procedure. 

Peaty won the last of Tuesday’s nine heats in Kazan, clocking 26.68.

The 20-year-old, who beat Van der Burgh to win the 100m breaststroke title on Monday, said of his heat: «I just went out there and had fun and didn’t take it that seriously.
