British swimmers staked their claims for Paralympic places with some strong displays at the British International Championships in Sheffield.
Louise Watkin (S9), Francesca O'Connor (S7) and Sean Fraser (S8) all set new European marks in the 100m freestyle.
There were also European bests for Heather Frederiksen (S8) and Stephanie Millward (S9) in the 100m butterfly and Lizzie Simpkin (S9 50m butterfly).
The GB swimming team for Beijing is set to be announced later this week.
There were also a host of British records set across the three-day meet which was the second and final chance for swimmers to post qualifying times for Beijing.
Among those who were on form were newcomer Sam Hynd, who improved his own British mark in the heats of the men's 100m freestyle.
The 16-year-old had beaten his own S8 400m freestyle world best on Friday and followed that up by clocking one minute 2.16 seconds over the shorter distance.
"I'm delighted with the way the whole weekend went for me," he told BBC Sport.
"Breaking the world record was the highlight but I had some good swims and I lowered the 100m record after not training sprints so that is a real positive."
Millward, a former GB able-bodied junior, who was struck down with multiple sclerosis shortly before the 2000 Sydney Olympics, returned to the sport six months ago and will be hoping to make the team for Beijing.
She also broke the European 100m backstroke mark in her keenly-contested S9 category.
"The trials have been tough but it has showed me that I can swim all of the races and all of the strokes, except the breaststroke, which I've always struggled with," she said.
"I was hoping to breack the backstroke record and I thought I might do well in the butterfly.
"The MS means I now know my body's limits but having the chance to compete at a Paralympics is like a second coming for me."
