Political parties for and against Catalonia's independence from Spain are making a final effort to convince voters as campaigning for a regional election comes to an end.
Thursday's election is being held in exceptional circumstances as it was ordered by the Spanish government when it seized control of the region.
It sacked its government and dissolved the regional parliament following a declaration of independence by MPs there on October 27.
Several of the ousted cabinet, including former Catalan president Carles Puigdemont, are campaigning from Brussels where they have sought refuge from Spanish justice while others are in jail in Spain on provisional rebellion charges.
Mr Puigdemont is to close his re-election campaign with a video speech to be relayed at a party rally in Barcelona.
