Protesters, many waving red and yellow Spanish flags, massed in the Plaza de Espana, a large square in the centre of the Spanish capital, and chanted “Pedro Sanchez, resign!”.
“The expiry date on this government passed a long time ago. It’s getting tiring,” Blanca Requejo, a 46-year-old store manager who wore a Spanish flag drapped over her back, told AFP at the demonstration.
The Popular Party (PP) called the rally after leaked audio recordings allegedly documented a member of the Socialist party, Leire Diez, waging a smear campaign against a police unit that investigated graft allegations against Sanchez’s wife, brother and his former right-hand man.
Diez has denied the allegations, telling reporters on Wednesday that she was conducting research for a book and was not working on behalf of the party or Sanchez. She also resigned from Sanchez’s Socialist party.
PP leader Alberto Nunez Feijoo has accused the government of “mafia practices” over the affair, and said Sanchez is “at the centre” of multiple corruption scandals.
“This government has stained everything, politics, state institutions, the separation of powers,” he told the rally, going on to urge Sanchez to call early elections.
The PP estimated that more than 100,000 people attended the rally, held under the slogan “Mafia or Democracy”.
