In what is described as a "ground-breaking initiative", UKAD has worked alongside FINA and other participating organisations to develop a "comprehensive and strategic test distribution plan" which has been executed in the seven months before Rio 2016.

The 14 other NADOs include the Spanish Anti-Doping Agency, the French Anti-Doping Agency, Anti Doping Denmark, Anti-Doping Authority Netherlands, Anti-Doping Singapore, the Australian Sports Anti-Doping Authority and the Canadian Centre for Ethics in Sport.

Completing the list is Drug Free Sport NZ, the Japan Anti-Doping Agency, the Korea Anti-Doping Agency, the German Anti-Doping Agency, the South African Institute for Drug Free Sport, the Swedish Sports Confederation and the United States Anti-Doping Agency.

FINA and the 15 NADOs are said to have made their best efforts to conduct five to seven out-of-competition tests for each nation’s top 10 world-ranked male and female swimmers, in every aquatic discipline held at the Olympic Games, since January 1.

A key part of the process, which is due to continue until the day of the Rio 2016 Opening Ceremony on August 5, is the sharing of relevant intelligence among the partner organisations.

The NADOs have taken the lead on testing swimmers in their individual countries, while it is claimed FINA coordinated testing for the top swimmers in nations outside of the partnership.

The initiative was created by FINA and the partner NADOs in a bid to ensure clean and fair competition during Rio 2016.  

"The pre-Games collaboration between FINA and 15 National Anti-Doping Organisations is an innovative approach for the anti-doping community," said UKAD chief executive Nicole Sapstead.

"I am delighted that a major International Federation has actively engaged with, and sought support from, a large number of NADOs in order to share and effectively use our combined resources.

"By working together, everything is being done to safeguard the integrity of the swimming competition at this year’s Olympic Games.

"I am confident that this project will serve as a catalyst and a blueprint for future collaborations.

"At a time when the spirit of sport is in danger of being eroded, initiatives like this one stand to show that the global sporting community needs to work together to deliver effective and targeted programmes to protect everyone’s right to clean, fair and honest sport."

FINA executive director Cornel Marculescu added: "FINA strongly believes in this initiative, working together with these leading NADOs from all around the world.

"It further demonstrates FINA’s commitment towards a coordinated global effort, in preparation for the 2016 Rio Olympic Games.

"FINA is confident that the plan developed to support this initiative and its execution have been effective, helping protect clean athletes training for the pinnacle of achievement in our sport.

"FINA will increase its cooperation and partnerships with these NADOs in the coming years.

"FINA will also continue the rigorous efforts to fight doping in aquatic sports through to the end of the year and in the months prior to the FINA World Championships in Budapest 2017."

Earlier this week, FINA banned seven Russian athletes from competing at Rio 2016 in the wake of the International Olympic Committee’s (IOC) decision not to impose a blanket ban on the nation following the release of the explosive McLaren Report into doping in the country.

Yuliya Efimova, the 100 metres breaststroke world champion who harboured strong hopes of winning a medal at Rio 2016, has been included on the list as a result of the IOC banning athletes from the scandal-hit country who had previously served a drugs ban.

The 24-year-old served a 15-month suspension in 2014 after testing positive for the anabolic steroid dehydroepiandrosterone and was implicated in the meldonium scandal earlier this year before her provisional ban was lifted.

Efimova's agent has declared she will appeal her ban from Rio to the Court of Arbitration for Sport, who have ruled twice previously that lifetime bans for a single doping offence are unlawful.

FINA President Julio Maglione claimed the World Anti-Doping Agency Independent Commission "exceeded their power" when compiling the McLaren Report.

The Uruguayan, now an honorary IOC member after exceeding the upper age limit last year, believes that the IOC themselves should have handled the matter.
