I'm torn between "Every people deserves the right to self-determination" and "Catalunya is richer than Spain, so it's the bourgeosie wanting to split off from the poors and pay less tax"

Independence movements in post-WW1 Europe also mostly produced right-wing nationalistic countries with short-lived Hungarian Soviet Republic as the only exception (that got crushed by other newly formed countries).
Former colonies is murkier question, but even there things often didn't improve for the left (although interference from imperial powers often played a decisive role in shifting the political dominance to rightists there).
