Tom Dean and Duncan Scott delivered gold and silver in the men’s 200m freestyle, the first British male one-two in the pool since 1908.
That came after Georgia Taylor-Brown secured a brilliant silver in the early morning triathlon, with the Mancunian looking right at home in the horrible conditions as a tropical storm swept into the Japanese capital.
There was disappointment for the hosts, though, as Naomi Osaka suffered a third-round exit at the hands of Marketa Vondrousova in the women’s tennis singles.
Here the PA news agency takes a look at day four’s action so far, and Britain’s further prospects.
What’s happened today so far?
Taylor-Brown overcame a flat tyre to take silver in the rain-soaked women’s triathlon, with the world champion making up three places in the 10-kilometre run to the finish. But there would be no catching Flora Duffy, who looked like the class of the field as she made made history by winning Bermuda’s first ever Olympic gold medal. Attention then turned to the pool when Dean and Smith finished strongly to celebrate a famous one-two. Great Britain suffered a 33-7 defeat to Olympic champions Fiji in their rugby sevens Pool B decider, though their ticket to the quarter-finals was already booked.
