Double world champion Adam Peaty has admitted that he could not "ask for more" after winning gold in the 50m breaststroke final in Kazan today.
The 20-year-old, who won 100m breaststroke gold earlier this week, set a new world record of 26.42s in the 50m non-Olympic event yesterday.
Today, Peaty went head to head with South Africa's Cameron van der Burgh in the final and managed to come out on top.
"I got the world record yesterday and secured the title today - I couldn't really ask for more," Peaty told reporters.
Britain have won six medals so far in the Championships.
