EX-Junta leaders Manuel Chaves and Juan Antonio Grinan will be prosecuted in the €855 million ERE redundancy payment scandal.
After a five-year investigation, Judge Alvaro Martin has ruled that they should stand trial with 24 other PSOE officials, over their involvement in diverting funds intended for the unemployed.
The news comes as a hammer blow for the PSOE, in the run up to elections.
The judge believes that they were clearly linked to a scandal that saw millions being syphoned off for bogus companies and redundancies between 2001 and 2010.
The trial is scheduled to take place in January 2017.
