Paralympian Heather Frederiksen explains failed doping test

Paralympic swimming champion Heather Frederiksen, who failed a doping test in 2009 after she used an inhaler "to save my life" during an asthma attack, tells BBC Sport's Chris Mitchell that she would have no hesitation in making the same decision again.

The 25-year-old was banned from the sport for six months after she tested positive for a raised level of Salbutamol - a drug she insists she needed to keep her alive - following an asthma attack at the IPC European Championships in Reykjavík.

Frederiksen is competing at this year's championships in Berlin and will be hoping to add to the gold she won in the S8 100m backstroke and silver in the S8 50m freestyle when she competes in the 400m freestyle S8 on Tuesday and the 100m freestyle on Friday.
