Prime Minister Hun Sen has been the leader of Cambodia since 1985, making him one of the longest-serving prime ministers in the world. He is a member of the Cambodian People's Party and has played a significant role in the country's political landscape, particularly after the end of the Khmer Rouge regime. Under Hun Sen's leadership, Cambodia has experienced economic growth and development, but his government has faced criticism for human rights abuses and suppression of political opposition. Despite these controversies, he remains a dominant figure in Cambodian politics and has maintained a strong grip on power through various elections.
