Team GB's men's medley relay squad won Britain's sixth medal of the Rio 2016 Olympic Games swimming meet, with Adam Peaty adding a silver to his individual gold.
Peaty, along with Chris Walker-Hebborn, James Guy and Duncan Scott finished behind a Michael Phelps-led American team in the race to win Britain's fifth silver of the meet, making it the most successful for Team GB since 1908.
Trailing after the backstroke, Peaty got GB back into the race, edging to the front with a 56.5 second breaststroke split - faster than his own world record. Guy held off Phelps for 50m but the American team was just too strong in the closing stages.
“I was a man on a mission. I knew the Americans would go out fast," Peaty said. "Chris did and amazing job, so when I dived in I had the composure and control.
"It was absolutely amazing to get that [56.5s] split. Hopefully that’s a message to the rest of the world for four years time where James and Duncan will be a lot more mature, have a lot more muscle, and hopefully if Chris decides to carry on he’ll be a lot faster. We’re looking at a very good relay coming together."
Earlier, Fran Halsall added to Britain's growing list of fourth-place finishes, with less than a tenth of a second separating her from the gold medal in the 50m freestyle final.
“It’s disappointing not to come away with the result I wanted but I’ve done everything I could this season to give myself the best shot. It didn’t work out how I wanted it to on the day," she said.
“It was a strong field and it didn’t go to form with who you thought would be there or thereabouts, so it was anyones for the taking but unfortunately I just couldn’t get my hand on the wall quick enough tonight."
Halsall returned to the pool for the women's medley relay, where Britain finished seventh in a race won again by the USA - the country's 1000th Olympic gold medal.
