Spain’s Teflon Prime Minister Pedro Sánchez swept to power seven years ago, vowing to clean up Spanish politics.

Now his Socialist party (PSOE) is engulfed in a corruption scandal involving prostitutes, public contracts, kickbacks, secret recordings, a former nightclub bouncer and a porn star.

His wife faces a separate investigation into allegations of influence-peddling, and there are claims that party officials created a job especially for his musician brother David.

Mr Sánchez’s enemies call him the “dog” because they say he is impossible to get rid of, but the graft scandal is now threatening to finally bring him down.

Europe’s most influential Left-wing leader is well aware of the risks, and the irony, of his invidious position.

Mr Sánchez ousted his scandal-hit conservative predecessor, Mariano Rajoy, by winning a vote of no confidence against him in 2018.

Spain’s National Court had ruled that Mr Rajoy’s Partido Popular (PP) was guilty of “institutional corruption”.

Mr Sánchez promised a new era of “democratic regeneration” as he cobbled together a coalition of communists, separatists and former terrorist organisation Eta’s political wing to grab power.

His grip on Spain’s government has not slipped in the years since, despite the recent massive blackouts, deadly floods in Valencia, or the allegations about his family.

His taste for woke politics has enraged the Spanish Right and he has clashed with Donald Trump and refused to commit to a new Nato defence spending target.

Such controversies bounce off the bulletproof prime minister thanks to the deeply polarised world of Spanish politics.

None of the rag-tag bunch of Leftists propping up his government want to be the one to break ranks for fear of handing power to a coalition of the PP and the far-Right Vox.

But the pressure is building on the handsome Madrileño after weeks in which his Socialist party has been roiled by seedy revelation after grubby exposé.
