Zimbabwe's president Robert Mugabe has turned 92. Dubbed as Africa's oldest leader, he was born in 1924 and has been leading the country for more than three decades. When Zimbabwe became independent in 1980, Mugabe became prime minister and assumed the office of president in 1987.

The leader was awarded the China's 2015 Confucius Peace Prize for "contributing to building the government, economy and order in the country while continuing to work at the age of 91 actively for African peace". However, he has been often criticised over allegations of corruption and crackdown on human rights, with right groups warning he continues to violate human rights, despite the implementation of a new constitution in 2013.

As thousands of people are expected to join celebrations for the leader's 92nd birthday, IBTimesUK looks at some of Mugabe's most famous and controversial quotes.
