Adam Peaty has become the first British swimmer in history to retain an Olympics gold medal with victory in the 100m breaststroke.
The 26-year-old, who set a new Olympic record in the pool at Rio 2016, was the comfortable winner in the event, clocking a time of 57.37s to notch up Team GB's first gold in Tokyo.
The result means that Peaty now holds the 16 fastest times in history over the 100m distance, having broken the world record five times - including the first ever sub-57s finish.
Dutch swimmer Arno Kamminga was Peaty's nearest contender, finishing on 58s for silver, while Nicolo Martinenghi was good for the bronze.
Peaty's teammate James Wilby finished in fifth, clocking a time of 58.96s in his debut Games appearance.
