MADRID (AP) — Spain’s Supreme Court on Thursday found the country’s attorney general guilty of leaking confidential information about the boyfriend of a leading conservative politician and government rival.

The court banned Attorney General Álvaro García Ortiz from his post for two years.

The decision is a blow to Prime Minister Pedro Sánchez, who defended García Ortiz during the monthslong investigation and court case.

García Ortiz was accused of having leaked an email to journalists with personal information about Alberto González Amador, when the businessman was under investigation for alleged tax fraud. That tax inquiry remains open.

González Amador is the partner of Madrid’s influential regional leader Isabel Díaz Ayuso, one of Spain’s main opposition leaders.

García Ortiz denied any wrongdoing.

In addition to being removed from his post, the court ordered that he pay 7,300 euros ($8,400) in fines, 10,000 euros ($11,500) in damages to González Amador and the court fees.

The trial earlier this month gripped Spanish media.

This was the first time in Spain’s modern history that a top prosecutor faced a criminal trial. The case is one of several that have implicated people close to Sánchez.
