The Agence Bretagne Presse carries the results of the first round of votes to the French parliament from Brittany (in French, of course). Nationalist politics in Brittany is incredibly fractious and has been since the 1970s. The Unvaniezh Demokratel Breizh (UDB) remains the largest party but it is a regionalist one (à la Plaid Cymru) and largely competes as part of shifting electoral alliances with other parties (most of which are “pro-French”). So far it has had mixed results electorally and this looks unlikely to change anytime soon. Their main rivals are the nominally Breton republican Strollad Breizh who have made relatively little impact at the ballot box. There are others such as the long-standing if all-but-defunct Emgann, not to mention the newer Breizhistance (which had a some modest success in this election as part of a wider Left coalition – spoiled by post-election disagreements in classic Breton style).
Of course France’s electoral system, which favours large establishment parties, doesn’t help but unfortunately some blame must attach to Breton nationalists themselves.
