International Atomic Energy Agency Director General Yukiya Amano is the sole candidate in the next election for IAEA chief, an agency official said Monday, paving the way for his re-election to a second four-year term from December.

The deadline for the nomination of candidates was Dec. 31.

"The chairman of the board informed IAEA member states today that he received no candidature other than the incumbent director general, Yukiya Amano," IAEA representative Gill Tudor said Monday.
