According to the organizers, around 120,000 people took part in the demonstrations, while local authorities estimated the number at around 40,000.
The background is the corruption allegations involving people close to the Spanish Prime Minister. Begoña Gómez, the wife of Pedro Sánchez, has been formally accused of several corruption offences. In addition, Pedro Sánchez's brother David is the subject of a corruption indictment.
Prime Minister Pedro Sánchez has on several occasions dismissed the accusations against his wife and brother as being politically motivated.
In addition, former Transport Minister José Luis Ábalos, who has also been a close associate of the prime minister, is awaiting a verdict in another corruption case.
