TOM DEAN led a GB one-two to win a brilliant 200m race at the Tokyo Aquatics Centre.
The 21-year-old Londoner had been an outsider in the field, with Scotland’s Duncan Scott the fastest qualifier.
But on a dramatic final leg, the pair came from third and fourth to take gold AND silver.
Dean broke the British record in 1:44.22, touching just four hundredths of a second ahead of his team-mates.
It meant the 24-year-old Glaswegian just missed out on his bid to become Scotland’s first swimming gold medallist since David Wilkie in 1976.
But nothing could deny Dean his stunning triumph.
Scott, third behind now-banned drugs cheat Sun Yang of China at the 2019 world championships, knew this was his chance of glory.
He was only sixth at the halfway mark, trailing Sunwoo Hwang of Korea.
But they began their moves in the third 50m, with Dean moving up to third and Scott, seemingly too far behind, in fourth.
But the pair then blitzed through the last 50m.
Scott, powering through the field, looked set to clinch gold.
Dean, though, came again, just getting the touch to become Britain’s second Olympic swimming champion of Tokyo 2020.
