PSOE suspends José Luis Ábalos as a party member after he refuses to leave his seat in Congress.
Ábalos will join the Mixed Group, weakening the already fragile parliamentary majority of Pedro Sanchez's government.
Although Ábalos faces no judicial charges, he's directly linked to the Koldo case, suspected of corruption.
Shadows of suspicion are increasing over PSOE, with the European Prosecutor's Office investigating possible misappropriation of funds in the Government of the Balearic Islands.
PSOE still has many questions to answer about its knowledge and complicity in this corruption scandal.
Conclusion: Although PSOE has shown decisiveness in the face of internal corruption, shadows of doubt remain about their implication and handling of these cases.
