Vizer, who has headed the IJF since 2007, will serve another four-year term after he was elected unopposed at the hybrid IJF Congress in Budapest. 

He expressed his thanks to all members who voted for him after the result was confirmed.

"During all these years it has been a pleasure to work with all of you in peace, with friendship and unity," said Vizer.

"Those are the pillars of stable development.

"It was an honour to work for the development of judo through discipline, respect and loyalty.

"Until now we have improved the judo level so much and have shared its values worldwide and we will continue to achieve great things together.

"Thanks to the outstanding cooperation with the International Olympic Committee, we will have for the first time a team event, including a refugee team, at the Tokyo Olympic Games this summer and for the editions to follow in the future.

"All of you can be proud of what we have achieved.

"Together for the next four years, we will do better and we will support the National Federations and continental unions even more.

"I believe that through unity, trust and solidarity we can raise judo to the next level.

"That is what we are going to do, starting from today."

He first took up the position of President in 2007, succeeding South Korea's Yong Sung Park.

The Congress was translated live into six languages, offering English, French, Spanish, Arabic, Russian and Hungarian channels.
