Oscar-winning Casey Affleck, who has been accused of sexual harassment by female crew members on earlier films, has withdrawn as a presenter at the 2018 Academy Awards, a spokeswoman for the organization said on Thursday.

Affleck, 42, who won the best actor Oscar last year for his performance in the family drama "Manchester by the Sea," was expected to present this year's best actress award in keeping with Academy of Motion Picture Arts and Sciences tradition.

"We appreciate the decision to keep the focus on the show and on the great work of this year," the academy spokeswoman said.
