A former minister and senior member of Spain’s Popular Party (PP) had  never thought her political aspirations would end up like this.  She has to resign from her roles after an investigation revealed their involvement in “illegal fiscal support” act in the Madrid region.

Esperanza Aguirre, 64, PP head in Madrid and a former education and culture minister under then premier Jose Maria Aznar said: “The seriousness of this information, although it has not been proven, led me to present my resignation,”

On Thursday, an investigation was laid down at the the headquarters of acting Prime Minister Mariano Rajoy’s party and industrial group Villar Mir. Police recovered documents by a former deputy PP head in Madrid, Francisco Granados, which had details of the illegal funding.

In a conference on Sunday, Aguirre said that the pressure of allegation had made her  resign although she insists that she had no role in the financial corruption.

Corruption is killing us. I don’t have any direct responsibility, but I understand that I have a political responsibility.” said Aguirre in a report by The New York Times.

On Friday, she was interrogated for her involvement in the “alleged misappropriation” – by members of the Madrid chapter of the party. The party was stained after repeated scandals reported in its four year of power.

She served as regional government head of Madrid between 2003 and 2012. In between she was not charged of any crime, but called to give evidence in an inquiry in October 2105.

While other PP members are yet to be questioned by a judge on how the data in the computer hard drives of party treasurer Luis Barcenas was cleaned before investigator could take it for probe, according to a report by Yahoo News.

The new corruption revelation has left a clear ground for two new political parties: Podemos on the left and market friendly Ciudadanos on the centre-right.
