According to Article 46 of the Hong Kong Basic Law, elections for the Chief Executive are held every five years. An 800-member electoral college called the Election Committee is elected by businessmen and professionals (those eligible for functional constituencies, with less than 180 000 eligible voters), and some other sectors of the society, with each of the twenty-eight sectors of the economy receiving a set number of electoral votes. The eligible voters in each sector vote directly for the electors, who in turn cast ballots for Chief Executive.
