CATALAN president Artur Mas is facing criminal charges following the region’s unofficial independence vote.
Prosecutors are to file the charges against the leader, after the non-binding vote went ahead on November 9 despite fierce opposition from the government.
More than 81% of those who voted were in favour of independence, leading Mas to insist he would push for an official referendum.
Joana Ortega, Mas’ deputy, also faces charges, as well as Catalan Education Minister Irene Rigau.
Accusations range from disobedience and perverting the course of justice, to misuse of public funds.
Out of a possible 5.4 million people, 2.3 million took part in the vote.
The case will be put before the High Court of Justice in Catalunya.
