South Sudan’s President Salva Kiir has banned anyone from singing the national anthem unless he is present, according to a government minister.

Information Minister Michael Makuei told AFP news on Monday that different leaders and institutions were playing the anthem at whim, which was an abuse of the national tune, written shortly before independence in 2011.

"For the information of everybody the national anthem is only meant for the president, in a function only attended by the president, not for everybody," Makuei said.

"We are seeing now even a minister, undersecretary, even governor or state minister, whenever there is a function, the national anthem is sung."

He said Kiir’s order was passed during a cabinet meeting on Friday.

Makuei said that with the exception of South Sudan’s embassies, which represented the president, and schools where children are taught the anthem, no one was allowed to sing the song in Kiir’s absence.

The minister said that military leaders had also been banned from addressing the public when in uniform.

He did not give details on what the punishment would be if the orders were not followed.

"These are orders and of course when you disobey the orders of the president then you carry your cross," Makuei said.
