Fresh from securing seven victories at the previous World Cup event in 2008 Olympic host city Beijing, Hosszú was again the star performer, while South African Chad le Clos picked up two wins.

Hosszú, nicknamed the "Iron Lady", reigned supreme in the women's 50 metres backstroke in a time of 26.35sec, touching the wall in front of Daryna Zevina of the Ukraine and China's Cheng Haihua.

The 27-year-old Hungarian, who has put in a series of superb displays since Rio 2016, enjoyed particular success in the freestyle events, winning the 200m race in 1min 54.37sec, which proved enough to beat Australian Madeline Groves.

China's Fang Yi rounded off the podium as she took home the bronze medal.

Hosszú then wrapped up a hat-trick on day one of the event in the Emirati city by clocking 8:27.45 on her way to victory in the 800m freestyle competition.

Her time was comfortably quicker than eventual silver medallist Fang, while Slovenian Spela Bohinc came through to seal bronze.

The fourth and final triumph for the Hungarian came in the 200m individual medley, one of her preferred events and a race she won gold in at Rio 2016, as she clocked 2:05.87.

Compatriot Zsuzsanna Jakabos, a European 4x200m freestyle champion, was second, while bronze went to Russia's Yuliya Efimova, who was booed during the Olympics after she was cleared to compete despite having previously served a doping ban.

Le Clos, who shot to fame at London 2012, triumphed in both the men's 50m and 200m butterfly competitions.

The South African posted a time of 22.08 to beat Britain's Benjamin Proud over one lap of the pool, with team-mate Roland Schoeman earning the bronze medal.

The three-time world champion then mastered the 200m discipline, touching the wall in 1:49.71 to oust Japan's Daiyo Seta and Philip Heintz of Germany, silver and bronze medallists respectively.

Action at the Dubai leg of the FINA Swimming World Cup concludes tomorrow.
