In the last election, the parties with the most votes were PSC (23,04%), ERC(21,3%) and JxCat (20,04%). PSC is unionist, where ERC and JxCat are separatist. Ciutadans (radically unionist) merely got 5,57% of the votes.

You might be thinking about the 2017 election, but even then, the fact that Ciutadans had the most votes had to do with the pro-independence parties being split.
In the las regional elections party with the most votes was a non-independence party: Ciutadans.
