Popular Party (PP) secretary general María Dolores de Cospedal is expected to testify before the High Court on Wednesday over allegations that she received bonus payments on top of her regular salary from a slush fund controlled by the party's ex-treasurer, Luis Bárcenas.
It will be the first time that a top party official offers testimony in the ongoing criminal investigation into Bárcenas' allegations being carried out by High Court Judge Pablo Ruz.
The former treasurer, who is being held in preventive custody until his trial, stated last month that he gave De Cospedal some 60,000 euros in cash payments from 2008 to 2010. Added to her combined salaries as a member of Congress and regional premier as well as PP secretary general, De Cospedal has earned close to one million euros since 2006.
Ruz has also called in former PP secretary generals Francisco Álvarez Cascos and Javier Arenas, who Bárcenas claims have also collected bonuses on top of their regular salaries over the years.
