Diver Tom Daley and his partner Dan Goodfellow's bronze medal win has boosted Team GB's medal tally to four on day three of the Rio Olympics.
The pair faced what Daley called an "agonising" wait before having a celebratory splash in the pool on learning of their medal placing in the men's 10-metre synchro event.
Their success followed another bronze for Great Britain, thanks to Ed Ling in the men's trap shooting.
Daley, 22, said he and Goodfellow had not even expected to qualify for the Olympics, having worked together for less than a year.
The victory made up for Daley's disappointment at the London Games in 2012 when he and then partner Pete Waterfield took fourth place, missing out on a medal.
Speaking after the win in Rio, Daley said: "It was an agonising wait that felt like it was an eternity. We were stood there and knew we had done a good dive but were didn't know if we'd done enough.
"It was just one of those moments where I knew how I would feel if it came up on the scoreboard that we finished fourth and I knew how I would feel if we finished third.
"We were just waiting and waiting with replay after replay, then all of a sudden the scores came up, I pounced on Dan and I don't think he was quite ready for it and then before we knew it we were back in for a top bombing seventh dive."
Goodfellow, a 19-year-old from Cambridge, who moved into Daley's home in London in the build-up to the Games, said he knew they were under pressure, but tried to " block everything else out and focus on my dives".
Following the diving victory Daley's fiance Dustin Lance Black, who has been supporting him in Rio, tweeted his congratulations to the pair.
He wrote: "So proud of you my love!!!Congratulations @TomDaley1994 & @danngoodfellow!"
Goodfellow's mother Sharon said on Twitter that she had not eaten for 12 hours in the run-up to her son's event. She also retweeted a video of the pair finding out they had gained a medal which was captioned: "Can't get over this. So happy for them!"
The diving success comes after a historic win for Adam Peaty, who took gold in the men's 100 metres breaststroke, a silver for Jazz Carlin in the women's 400 metres freestyle and victory for Ling, who blasted his way to third place.
Speaking after the victory Ling said his achievement had been "a long time coming", adding that he hoped it was another of many medals for Team GB.
He said: "I think this is great for shooting. It is also another medal for Team GB which is fantastic and hopefully there is a lot more to come."
Team GB has another chance to pick up a medal in the pool thanks to swimmer Siobhan O'Connor. On day three of the games she qualified fastest for the 200m individual medley final with a new British record.
She will face Hungarian Katinka Hosszu, who has already won two gold medals at the Rio games, on Tuesday.
Meanwhile there was disappointment for Britain's men's gymnasts and women's rugby sevens team, both of whom missed out on medals.
The gymnastics team had looked likely to place third throughout their performance, but after three-time Olympic medallist Louis Smith came off the pommel horse during his routine they fell short, coming fourth.
On the pitch the women's rugby sevens suffered a convincing defeat to Canada in their bronze medal match, losing 33-10.
After becoming only the third Briton ever to reach the last 16 in the Olympic table tennis competition, Paul Drinkhall was forced out of the competition after losing to Belarussian Vladimir Samsonov.
Back in the pool, world champion James Guy narrowly missed out on a medal in the men's 200 metres freestyle. He placed fourth in a race won by China's Sun Yang.
Away from the sporting events, Rio police investigating illegal ticket sales said they had arrested two men.
Kevin Mallon - one of the heads of London-based ticketing provider THG Sport - was arrested with alleged fake tickets and is accused of conspiracy and helping sell tickets illegally.
The Olympic Council of Ireland said it had no knowledge of the two men arrested and is investigating why tickets allocated to the organisation were found on them.
