Spanish football federation chief Luis Rubiales has announced his resignation as president.
A Spanish prosecutor filed a complaint with the High Court against Rubiales last week for sexual assault and coercion over his allegedly unsolicited kiss on the lips of World Cup-winning player Jenni Hermoso.
Rubiales had also been suspended for three months from all football activities by FIFA pending an investigation by soccer's world governing body into his actions after Spain clinched their World Cup victory in Sydney on August 20.
"After the rapid suspension carried out by FIFA, plus the rest of the proceedings opened against me, it is clear that I will not be able to return to my position," Rubiales said in a statement on Sunday.
"Insisting on waiting and clinging... is not going to contribute anything positive, neither to the Federation nor to Spanish football. Among other things, because there are de facto powers that will prevent my return," he added.
He said he had also stepped down as a vice-president of European soccer body UEFA.
Rubiales has insisted the kiss, on Hermoso following Spain's World Cup win last month, was consensual but the case has sparked outrage among players and many in wider Spanish society.
He appeared to continue to defend his version of events while announcing his resignation.
"I have faith in the truth and I am going to do everything in my power to make it prevail," he said.
As Spain celebrated their grand final win against England at the FIFA Women's World Cup, Hermoso took to the podium to receive her medal.
While the world watched on, Hermoso accepted her prize, and in a fleeting moment, Rubiales grabbed her face and kissed her on the lips.
