Manuel Valls, former socialist prime minister of France, current member of French parliament... Is apparently planning to run for mayorship in Barcelona (yes that one in Catalunya). I couldn't presume to be an expert on Spanish politics, but as far as I know he doesn't have a strong political network there and he's already caught some verbal flak (by Puigdemont : "He's legally entitled to be candidate but he doesn't know the city. He knows France. To judge the man, just listen to what French citizens think of him", to paraphrase. As you would guess, Valls isn't terribly popular here). He was born there and I guess he has personal history with the city but it's hard to imagine he has any chance and it feels a bit arrogant to insert one self like this... Valls has never insulted his heritage, quite the contrary, but he's also always have been pretty aggressively French, in that tone of France being the vanguard for universalism and the Rights of Men, revolutionary prototypes for citizens of the world, secularism and national security.
I don't know what to think of it. Could be the height of hubris, could be exemplary Europeanism, probably both. Maybe he figures he has a chance because of the agitated situation (the recent autonomist crisis is out of the spotlight and on the backburner without having been really closed).
