N'DJAMENA (AFP) - Chadian President Idriss Deby on Monday appointed chief of staff Djimrangar Dadnadji as the country's new prime minister following the resignation of Emmanuel Nadingar, state radio announced.
"I have the honour to hand in... my resignation as prime minister, head of government, three years after you appointed me in this post. Today I have come to the end of my mission," Nadingar wrote in a resignation letter read out on the radio.
The radio also announced Dadnadji as his successor.
Nadingar, in office since March 2010, was re-appointed following disputed April 2011 re-election of Deby, who has held power since 1990.
Government reshuffles are a frequent occurrence in the landlocked African desert nation run with an iron fist by Deby, and premiers rarely last more than two or three years.
