Former Spanish Prime Minister Jose Luis Rodriguez Zapatero

Former Spanish Prime Minister Jose Luis Rodriguez Zapatero is being investigated for alleged influence peddling and related crimes, the country's High Court said on Tuesday.

Zapatero's office in Madrid was being searched alongside three other premises, the court said in a statement, adding the former premier had been summoned to testify on June 2.

Zapatero is a key ally of current Socialist Prime Minister Pedro Sanchez and the case piles more pressure on Sanchez, who is already dogged by a corruption investigation into alleged kickbacks involving key members of his inner circle, as well as probes involving his wife and his brother.
