YAOUNDE, April 12 (Xinhua) -- Already postponed from April 25 to May 16, the presidential and legislative elections in the Central African Republic could be postponed again, according to an official source.

The source close to the presidency told Xinhua on Sunday on telephone from Bangui, the capital of the Central African Republic, the new postponement had been justified by the authorities as a necessary guarantee for the success of elections.

Outgoing President Francois Bozize and ex-president Ange Felix Patasse, who came back from exile in Togo, had previously agreed on the polls will other politicians in an inclusive political dialogue held in Dec. 2008.

The election process has since met with disturbances from issues like persistent rebel movements, which still occupy parts of the territory, especially the north.

In addition, a boycott has been announced by opposition parties, which are calling for the return of peace before any voting operation is launched.

Bozize came to power on March 15, 2003 in a military coup to topple Patasse, who is today considered as a formidable opponent. Bozize was elected in May 2005 and is to run for his second term.
