Julio Cesar Maglione has been re-elected as president of FINA, swimming's international governing body, for a second four-year term.
The 77-year-old Uruguayan was standing unopposed at yesterday's FINA Congress in Barcelona, Spain, where the 2013 FINA World Championships are presently taking place.
Maglione replaced Mustapha Larfaoui as FINA president in 2009, having previously served the federation as vice-president and honorary treasurer. The Algerian had been in office for 21 years.
Last September, Maglione was re-elected as president of the Uruguayan National Olympic Committee for a fifth term. He has been a member of the International Olympic Committee since 1996.
Also at the congress, FINA members approved the introduction of mixed relays, featuring two men and two women, to official competitions.
The mixed relays will be included at a major event for the first time at the 2014 World Short Course Championships in Doha, Qatar.
Cornel Marculescu, executive director of FINA, told Reuters: "The feeling of everybody, swimmers and coaches and technical committee, is that this is a very interesting event with a lot of tactics involved. The most important thing is that the athletes are happy and I think that is why the decision was made.
"I think it's going to be very popular with the swimmers and this is the number-one criteria for me."
