Philippine President Rodrigo Duterte, whose rape jokes have sparked outrage in the past, drew fresh flak Tuesday after signing a law against sexual harassment, with campaigners saying his role as the "misogynist-in-chief" would make implementation challenging. Duterte, who has himself been accused of sexual harassment on multiple occasions, signed the law that prohibits behaviour such as catcalling and sexist slurs in April, according to the text released on Monday. The law imposes fines and, in some cases, prison sentences for sexual harassment in streets, schools and offices, including wolf-whistling, groping, misogynistic slurs, as well as uninvited comments or gestures referring to a person's appearance.
