SINGAPORE (Reuters) - Singaporeans are expected to return the People's Action Party to power in a July 10 general election, extending its unbroken rule since the Southeast Asian island's independence in 1965.

In that time, Singapore has had only three prime ministers: independence leader Lee Kuan Yew, his cabinet colleague Goh Chok Tong and Lee's son, the present prime minister Lee Hsien Loong.
