KIEV (Reuters) - Ukraine's top state prosecutor resumed his duties on Wednesday despite having formally resigned a month ago, prolonging the tenure of an official seen by the United States as an obstacle to tackling corruption.

Viktor Shokin had gone on holiday after quitting on the insistence of President Petro Poroshenko. His resignation needs parliamentary approval, but lawmakers have not set a date for a vote, nor has Poroshenko nominated a replacement.
