King continued her much publicised rivalry with Russia’s Yulia Efimova in the women’s 50 metres breaststroke, with both athletes seeking to secure their second individual title of the Championships.

Having triumphed in the women’s 100 metres breaststroke in a world record, King was able to repeat the feat over 50m by touching home in 29.40sec.

Efimova, the newly crowned 200m champion, claimed the silver medal in a time of 29.57 before the pair had a seemingly light-hearted conversation at the finish.

The pair’s rivalry emerged at last year's Olympic Games when Efimova was only granted permission to compete shortly before Rio 2016 by the Court of Arbitration for Sport.

She was initially barred due to an International Olympic Committee rule banning Russian athletes who had served doping suspensions.

Katie Meili, who had split King and Efimova in the 100m, took bronze for the United States in 29.99.

The home crowd were enlivened by the performance of Hosszú, who won her second gold of the Championships by triumphing in the women’s 400m medley in 4min 29.33sec.

Mireia Belmonte of Spain and Canada’s Sydney Pickrem rounded off the podium in times of 4:32.17 and 4:32.88 respectively.

Sweden’s Sarah Sjostrom concluded her outstanding Championships by clinching a third gold medal.

She finished the women’s 50m freestyle in a time of 23.69, touching out Ranomi Kromowidjojo of The Netherlands, who won silver in 23.85.

Simone Manuel of the US rounded off the podium in 23.97.

France celebrated their first gold medal in the Duna Arena, with Camille Lacourt winning the men’s 50m backstroke for the third consecutive World Aquatics Championships.

The 32-year-old touched home in 24.35 to take the gold, with Japan’s Junya Koga and American Matt Grevers completing the podium in 24.51 and 24.56.

Italy’s Olympic champion Gregorio Paltrinieri won the men’s 1,500m in the time of 14:35.85, although he was pushed by Ukraine’s Mykhailo Romanchuk, who claimed silver in 14:37.14.

Australia’s Mack Horton won bronze in 14:47.70.

Chase Kalisz won the men’s 400m medley in 4:05.90, with Hungary’s David Verraszto ending 2.48 behind the American in second.

Olympic champion Daiya Seto of Japan finished as the bronze medallist in 4:09.14.

The US concluded action in the pool with double relay gold, with their women’s 4x100m medley team setting a world record time of 3:51.55 in a dominant performance.

Russia impressed to win the silver medal in 3:53.38, while Australia took bronze by clocking 3:54.29.

Britain won the silver medal in 3:28.95, while Russia secured bronze in 3:29.76.

The final high diving event also took place today, with Steve Lo Bue of the US achieving a score of 397.15 points to win the event.
