A woman is suing her high-flying female Yahoo executive boss for alleged sexual harassment.
Software engineer Nan Shi claims Maria Zhang, a senior director of engineering at Yahoo Mobile, said she would have a 'bright future' at Yahoo if she had sex with her.
Miss Zhang denies the allegations.
A Yahoo representative said: "There is absolutely no basis or truth to the allegations against Maria Zhang. Maria is an exemplary Yahoo executive and we intend to fight vigorously to clear her name."
