Election to the Federal

His party gave up the vacant seat and wanted to go back into opposition. The claim of the most densely populated canton of Zurich to the Swiss Federal Council seat was uncontested, so that very few candidates ever came into question. The FDP ported Streuli, the Catholic Conservatives (now CVP) ported Emil scent exactly one day before election day.
