Spain’s Prime Minister Pedro Sanchez will break his silence Monday on whether or not he will resign in response to a graft probe of his wife that he says amounts to a campaign of harassment.

The 52-year-old, in office since 2018 and only reappointed to another term in November, is due to speak at 12:00 pm (1000 GMT) from the Moncloa palace in Madrid, his official residence.

Sanchez announced last Wednesday that he was mulling resignation after a Madrid court opened a preliminary probe into suspected influence peddling and corruption targeting his wife Begona Gomez.

“I need to stop and think whether I should continue to head the government or whether I should give up this honour,” he wrote in a four-page letter posted on X, formerly Twitter.
