The head of Brazilian Doping Control says he is confident all testing of samples during the Olympic and Paralympic Games will be carried out in Rio de Janeiro, despite political turmoil preventing the country's main laboratory from confirming its WADA accreditation.

SOUNDBITE: (English) Francisco Radler de Aquino Neto, Brazilian Doping Control Laboratory chief coordinator:

"Here we have what they call now the Brazilian Doping Control Laboratory which is the laboratory from the Federal University of Rio de Janeiro. We have been doing anti-doping analysis for almost 30 years now. We have been prepared with a huge investment from the Brazilian government to be able to cope with the challenge of doing the Olympic doping control analysis."

(on whether the laboratory is ready for the Olympics despite having its accreditation removed for a period of time):

"The laboratory was accredited in May 2015. So it was even before the testing events for the Olympic and Paralympic Games. Since then we have been working together with the ABCD in all doping control in Brazil and even the Olympic Games. We are ready, of course there is always more we can do up to the Games, but we now have the best equipment that you can have and the most experienced and trained experience that we will have during the Games. So we are ready for it."
