GENEVA (AP) — The head of the U.N. agency focusing on AIDS says he'll leave his post in June, an early departure announced a week after independent experts looking into sexual harassment at UNAIDS blasted its "defective leadership."

Executive director Michel Sidibe made the announcement during a UNAIDS board meeting Thursday in Geneva, said agency spokesman Mahesh Mahalingham, who could not immediately provide further details.

Sidibe's term was meant to end in January 2020. 

Last Friday, a panel of four experts cited a culture of impunity and a toxic working environment at UNAIDS, insisting that couldn't be changed unless Sidibe, who comes from Mali, resigned. The panel was created earlier this year following allegations of sexual harassment inside the agency.
