Great Britain claimed a fourth swimming gold at an Olympics for the first time in 113 years by winning the inaugural 4x100m mixed medley relay in a world-record time.
The British quartet of Kathleen Dawson, Adam Peaty, James Guy and Anna Hopkin won in three minutes 37.58 seconds.
China took the silver medal while Australia won bronze.
The gold is Peaty’s second in Tokyo after the 100m breaststroke while Guy also won the 4x200m freestyle relay.
“One word has changed the whole British team – belief,” said Peaty.
“We believe we can win, we believe we can get world records. If you have belief, you can build everything around that and we showed that here.”
