A Spanish judge on Tuesday summoned disgraced ex-football chief Luis Rubiales to testify on April 29 over an alleged graft scandal at the national federation when he was president, court documents showed.

The 46-year-old returned to Spain from the Dominican Republic on April 3 and was briefly detained by police at the airport as part of a probe into federation contracts signed since 2018, including one signed by Rubiales to take the Spanish Super Cup to Saudi Arabia.
