Spanish football federation chief Luis Rubiales quit his post on Sunday after three weeks of scandal over allegations he gave an unsolicited kiss to a player on the women's national team as they celebrated their World Cup victory last month.

Rubiales announced his resignation in a statement in which he said his position had become untenable.

His kiss of player Jenni Hermoso after the World Cup win in Sydney on Aug. 20 had caused outrage among players, government officials and many in wider Spanish society and raised questions over sexism in sport.

His decision to go came after further blows to his position in the last few days.

A Spanish prosecutor filed a complaint with the High Court against Rubiales on Friday for sexual assault and coercion.

The complaint - which came after Hermoso opted earlier in the week to lodge a criminal complaint over the incident - describes how Rubiales kissed Hermoso on the mouth "without her consent" while holding her head with both hands after Spain defeated England to clinch the World Cup.

Rubiales has said the kiss was mutual and consensual, and had until Sunday defied calls from players, government officials and others for him to resign.

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.

Reuters reached out to Hermoso's representative for comment on Rubiales' resignation, and they did not return the telephone call.
