Spain's socialist PM Pedro Sanchez announces he will NOT quit after five days of 'reflecting on his future' amid corruption probe into his wife

Spain's socialist Prime Minister Pedro Sanchez declared this morning that he will not quit as the country's leader after a period of reflection about his future.

Sanchez made the announcement five days after a court said it would investigate his wife, Begona Gomez, for influence peddling and business corruption, allegations he said were false and orchestrated by his right-wing opponents. 

The 52-year-old surprised both foes and allies alike when he said on Wednesday he was taking several days away from public duty to consider quitting amid the allegations, provoking large demonstrations from his supporters over the weekend.

Spanish politics was thrown into turmoil by the prospect of the PM standing down, potentially sparking another fractious parliamentary vote to choose a new prime minister or even a fourth general election in five years.

But after meeting with King Felipe VI this morning - a step that would have been necessary should he have decided to resign - Sanchez announced in a televised address that he had informed the monarch of his decision to stay on.

'I have decided to go on, if possible even stronger as prime minister. This is not business as usual, things are going to be different,' he said in a national broadcast. 

Sanchez voiced frustration at his 'powerlessness' to protect his wife from attacks last week, but said today that he had been encouraged to stay by widespread expressions of support over the weekend.

As news emerged that his wife was being investigated on Wednesday, Sanchez wrote in a four-page letter posted on X that attacks on his wife had 'crossed the line of respect of a prime minister's family life, with an attack on his personal life'.

'I need to stop and think whether I should continue to head the government or whether I should give up this honour,' he said.

Days later, thousands of supporters massed outside the headquarters of his Socialist party in Madrid chanting: 'Pedro, stay!'

Sanchez has said the move targeting his wife is part of a campaign of 'harassment' against them being waged by 'media heavily influenced by the right and far right' and backed by the right-wing opposition.

The public prosecutor's office on Thursday asked that the investigation be closed.

Sanchez, an expert in political survival who has made a career out of taking political gambles, suspended all his public duties and retreated into silence.

The court opened its investigation into Sanchez's wife in response to a complaint by anti-corruption pressure group Manos Limpias (Clean Hands), whose leader is linked to the far right.

The group, which has presented a litany of unsuccessful lawsuits against politicians in the past, said in a statement late on Wednesday that it had based its complaint on media reports and could not vouch for their veracity.

While the court did not give details of the case, online news site El Confidencial said it was related to her ties to several private companies that received government funding or won public contracts.

Sanchez has been vilified by right-wing opponents and media because his minority government relies on the support of the hard-left and Catalan and Basque separatist parties to pass laws.

They have been especially angered by his decision to grant an amnesty to hundreds of Catalan separatists facing legal action over their roles in the northeastern region's failed push for independence in 2017.

That amnesty, in exchange for the support of Catalan separatist parties, still needs final approval in parliament.

The opposition has since Wednesday mocked Sanchez's decision to withdraw from his public duties for a few days, dismissing it as an attempt to rally his supporters.

'A head of government can't make a show of himself like a teenager and have everyone running after him, begging him not to leave and not to get angry,' jeered Alberto Nunez Feijoo, leader of the right-wing opposition Popular Party, on Thursday.

Sanchez, he said, had subjected Spain to 'international shame'.
