* Supervisory board will meet few days later than Sept. 24
* EDF has no comment
(Adds detail, background)
PARIS, Sept 17 (Reuters) - A board meeting at French power utility EDF on who will replace chief executive officer Pierre Gadonneix will be delayed by several days from Sept. 23, sources close to the matter told Reuters on Thursday.
"It will clearly be postponed by a few days,", one of the sources said, without giving details on the reason.
EDF, the world's largest utility, declined to comment on the matter.
A source close to EDF had previously told Reuters the state-owned group's supervisory board would meet on Sept. 23 to adopt, among other things, a list of six representatives whose mandates will be approved or not by shareholders in November.
Gadonneix, whose mandate expires that month, or his successor, will be on this list. Gadonneix, 66, has been seen under threat since running foul of the government this summer over his calls for bumper rises in state-set electricity tariffs at a time of rising unemployment.
But magazine Challenges, in its Thursday edition, reported that France's economy ministry has advised President Nicolas Sarkozy to keep Gadonneix at the helm and appoint a deputy at his side, to take his seat in a year's time.
Sarkozy had now cast aside Veolia Environnement Chief Executive Henri Proglio, once a rumoured front-runner, as a possible new head of EDF, it said.
Alstom head Patrick Kron, Areva chief Anne Lauvergeon and GDF Suez Deputy CEO Jean-Francois Cirelli have also been cited as possible candidates to replace Gadonneix.
EDF shares closed 1.5 percent lower at 40.90 euros on Thursday.
