In accordance with Article 37, the Convention will enter into force with respect to Uzbekistan on the first day of the month following the expiration of a period of one month after the date of deposit of this instrument of ratification, that is to say on 1 June 2011.

According to WADA, the total number of UNESCO member states to have ratified the ‘International Convention against Doping in Sport’ has reached 158.

The International Convention against Doping in Sport is now the third most successful of all UNESCO conventions, which shows a remarkable commitment and unified approach from countries across the world.

UNESCO is made up of 193 member states, leaving just 35 who have not yet completed the process.

“We applaud the decisions of Uzbekistan and Gambia to come on board in the fight against doping in sport,” said WADA Director General David Howman.

“It is a remarkable achievement for WADA’s ideals to develop an accord with 158 countries around the world and a credit to our Governments department.

“If ever anyone has doubt as to the worldwide commitment to our cause, they need only to look at this figure. It sends out a very strong message that the world is united in its desire to rid sport of drugs.”
