Sports Minister Tracey Crouch said "everyone involved in sport must work together" following fresh claims of doping by Olympic athletes.
These are serious allegations and it is right they are being referred by the World Anti-Doping Agency (WADA) to its Independent Commission for investigation. I know UK Anti-Doping (UKAD), one of the best anti-doping agencies in the world, is also supporting this action, and has made it clear it will assist with WADA's enquiries.
UKAD has worked tirelessly to ensure athletes and sport are clean. But everyone involved in sport must work together to ensure we maintain the spirit of sport and prevent doping.
The IAAF says it will not rule out "any follow-up action necessary" over a report alleging widespread doping in the sport.Read the full story ›
Jessica Ennis-Hill has called on the IAAF and the World Anti-Doping Agency (Wada) to address the problem of doping after fresh claims of cheating.
"It is never good to hear of new possible doping offences in my sport, but if we are to stop a few athletes thinking cheating is acceptable, we have to explore all information that comes to light, however damaging it is for the sport as a whole", she said.
According to the Sunday Times (£), leaked data reveals that more than a third of medals - including 55 golds - have been won in endurance events at the Olympics and world championships by athletes who have recorded suspicious tests.
It is also alleged that a top UK athlete is among seven Britons with "suspicious" blood scores, while 10 medals were won at the London 2012 Olympics by athletes who have reportedly recorded dubious test results.
At least 800 athletes have recorded blood-test results described by an expert as "highly suggestive of doping or at the very least abnormal",the Sunday Times reports (£).

The data, which belongs to the IAAF but was released by a whistleblower, also reportedly reveals:
- More than a third of Olympic and world championships medals - including 55 golds - have been won by athletes with suspicious doping test results.
- It is also alleged that a top UK athlete is among seven Britons with "suspicious" blood scores.
- Ten medals were won at the London 2012 Olympics by athletes who have reportedly recorded dubious test results.
Officials at The World Anti-Doping Agency (Wada) said it was "very alarmed" by the latest claims which would "shake the foundation" of clean athletes across the globe.
Wada is very disturbed by these new allegations that have been raised by ARD; which will, once again, shake the foundation of clean athletes worldwide.
The ARD documentary, Doping - Top Secret: The Shadowy World Of Athletics, contains new allegations regarding widespread doping in international athletics.

Retired British sprinter Roger Black has spoken out in favour of new anti-doping rules after he suffered a defeat at the hands of drug cheats.
The double World Championship gold medallist explained to Daybreak how American sprinters robbed him and his teammates of "the moment" of victory.
"What they took away was the moment. We never experienced the moment. The moment where you're standing on the rostrum with three other teammates and celebrating to be the best in the world."
The new system of testing for doping in sport will have an "extremely deterrent" effect, world football body Fifa's chief medical officer has said.
Professor Jiri Dvorak said testers would now be able to freeze blood and urine samples so that scientists can re-test them later on, potentially using newer technologies to detect performance-enhancing drugs.
"There is a strong evidence that if you re-analyse the samples from past years that new methods would find them, this is an extremely deterrent method," he said.
"Most of the international federations decided to freeze the samples for a number of years.
