Sounds like nobody has a real answer yet
"The accusations against Mr Sánchez’s wife, Begoña Gómez, were brought against her by the organisation Manos Limpias (Clean Hands), led by a man linked to the far-right called Miguel Bernad.
On Thursday, Madrid’s public prosecutor called for the probe to be shelved for lack of evidence. Manos Limpias also acknowledged the allegations might be incorrect because they were based on online newspaper stories - one of which has already proven to be false."
What a hero
Well the far-right person whose organization made the allegations had already admitted publicly that the allegations came from online newspapers, and that one of them has already proven to be made up.
So, oddly yes.
He threw a tantrum, took a 5 day vacation, and made everyone wait for nothing. Nothing heroic about that.
