Prince Khalifa bin Salman Al Khalifa (Arabic: ????? ?? ????? ?? ??????) (born 24 November 1935) is the Prime Minister of Bahrain since 1969, taking office nearly two years before Bahrain's independence on 15 August 1971.
He is the longest-serving current prime minister in the world.
He still retains his post, although under the 2002 Constitution he has lost some of his powers, with the King having the authority to appoint and (along with the Bahraini parliament) dismiss ministers.
He is the paternal uncle of the reigning King Hamad bin Isa Al Khalifa and granduncle of the Crown Prince Salman, since he is the younger brother of the former Emir Isa bin Salman Al Khalifa.
