Fran Halsall claimed two medals in Berlin, where 10 world short-course records were broken at the World Cup meet.

Halsall, 19, led Great Britain's charge with silver in the women's 100 metres freestyle before touching in third behind a world record swim from Holland's Hinkelien Schreuder in the 100m individual medley.

Schreuder's mark was one of 16 world records to fall over the two days of competition, with the new regulations on the swimmers' costumes not due to begin until January 1.

Michael Phelps, the 14-time Olympic champion, again chose to wear a textile suit that will fall under the new regulations and, after missing out on the final of the 200m freestyle on Sunday morning, had to content himself with second in the 200m IM final.

South Africa's Darian Townsend claimed the title in a world record time of one minute 51.55 seconds - beating Phelps by 1.85secs.

Britain's other competitors in action on Sunday saw Elizabeth Simmonds finish fourth in the final of the women's 100m backstroke - won in world record time by Japan's Shiho Sakai - while Ross Davenport touched in fifth in the men's 200m freestyle final.

Fifteen-year-old Jessica Thielmann also impressed to finish 12th in the women's 400m IM.
