A proposal to add women's lightweight single sculls to the Olympics has failed to gain approval from rowing's governing body.
Rowing federation FISA says the Canadian proposal was withdrawn at the federation's congress in Copenhagen over the weekend.
There are currently six women's events on the Olympic program, with eight for men. Meanwhile, the congress approved the reintroduction of the women's four event for the world championships.
The event had been removed after the 2011 worlds. The congress also rejected a proposal to eliminate the men's coxed pair event. FISA President Denis Oswald, who has held the position for 24 years, announced he would seek re-election at the next congress on September 2 for a ''transitional'' period of six to eight months.
The Swiss official had previously indicated he would step down then. National federations were asked to nominate possible candidates for Oswald's successor by June 2.
The vote will be held on Sept. 2 in Chungju, South Korea, at the world championships. Oswald, who is also an IOC member, has said he is considering running to succeed Jacques Rogge as IOC president.
The IOC election will be held September 10 in Buenos Aires, Argentina.
