2011 Singaporean presidential election
All four eligible candidates are Chinese Singaporeans, and by coincidence, all have the surname of Tan. This meant that by Nomination Day, it was certain that Singapore's next president will be named "President Tan", and that Singapore would have a president of Chinese heritage, for the first time since Ong Teng Cheong stepped down from the Presidency in 1999.
