UK Queen world's oldest head of state after Mugabe steps down
Queen Elizabeth, at 91, is already Britain's longest reigning monarch, a record she took from her great-great-grandmum Queen Victoria.
Tuesday saw Robert Mugabe end his 37-year reign as Zimbabwe’s president when he resigned under pressure form the country’s militia.
While Mugabe’s departure is being hailed as a historic move for the African nation, it also made Queen Elizabeth the world’s oldest head of state.
At 91, Queen Elizabeth is already Britain’s longest reigning monarch, a record she took from her great-great-grandmum Queen Victoria in September 2015.

Technically second in line to the throne, he was put into office after it emerged that Sheikh Jaber's natural successor, Sheikh Saad, was unable to take the oath.
Raul Castro, President of Cuba at 86, Paul Biya, President of Cameroon at 84, Michel Aoun, 84, President of Lebanon, 83-year-old Akihito, the Emperor of Japan; and King Salman, 81, King of Saudi Arabia are some of the other elderly heads of states.
