Since the constitutional amendments made in 2016, a presidential election will be reserved for a community in Singapore if no one from that community has been President for any of the five most recent terms of office of the President. The communities are the Chinese community, the Malay community, and the Indian or other minority communities. Candidates are required to satisfy the usual qualification criteria. The 2017 election was the first reserved election, and was reserved for the Malay community.
