Valls to 'contribute' to Barcelona politics despite election loss After an unsuccessful bid to become Barcelona's mayor, former French prime minister Manuel Valls says 'he is always ready to help constitutionalism' at a press conference in the Spanish city. Barcelona's acting mayor Ada Colau was re-elected, beating a Catalan separatist who had come first in municipal polls, after reaching a deal with the socialists and getting unexpected support from Valls.
