Hermoso gave her testimony yesterday and the complaint will be processed “as soon as possible”, the prosecutor added.

With the complaint, Rubiales could face criminal charges in addition to the ongoing inquiry by Spain’s top sport court for “serious misconduct” and an investigation by world football governing body Fifa, who have provisionally suspended Rubiales from office.

Neither Hermoso’s representatives nor Rubiales were immediately available for comment.

Rubiales grabbed Hermoso’s head and kissed her on the lips during the medal-giving ceremony that followed Spain’s 1-0 victory over England in the Women’s World Cup final on Aug 20.

Late last month, the prosecutor for Spain’s high court said Rubiales could face a sexual assault charge, which carries a prison term of between one and four years, if Hermoso were to file a complaint.

The high court has jurisdiction over the case as the incident took place abroad – in Sydney, Australia.

Hermoso said she did not want to be kissed, and that she felt “vulnerable and a victim of an aggression”.

Rubiales, who has so far refused to resign despite heavy pressure, said the kiss was “spontaneous, mutual, euphoric and consensual”.

Rubiales’ behaviour has sparked outrage in Spain and abroad.

He also grabbed his crotch while standing close to Spain’s Queen Letizia and her 16-year-old daughter during the final match.
