Nominations for the FEI Presidential election closed at midnight on May 1.
Princess Haya, who was elected to the FEI Presidency in 2006, is seeking a second four-year term to take her through to the 2014 General Assembly.
The Swedish Equestrian Federation announced on Thursday it had nominated Sven Holmberg, who is currently first vice-president of the FEI, a position he has held since 2006.
Henk Rottinghuis, of The Netherlands, was elected as a member of the FEI Audit and Compliance Committee at the 2009 General Assembly.
The FEI Presidential election will take place at the 2010 FEI General Assembly, which will be held in Chinese Taipei on 5 November. National Federations will vote by secret ballot at the General Assembly.
There are 133 National Federations in the FEI, and a candidate requires a two-thirds majority to win the election.
In 2006 three candidates were declared for the FEI Presidency, marking the first time that there had been an election for the post. The three candidates in 2006 were HRH Princess Haya, HRH Princess Benedikte of Denmark (DEN) and the then First Vice-President Freddy Serpieri (GRE).
