Together they represent a minority of votes and a minority of seats in the Catalan parliament. Others such as Ciutadans, and the People's Party of Catalonia, which had 25.4% and 4.2% of the vote respectively in the 2017 Catalan regional election, have always opposed the notion of Catalan self-determination.
