Convergence and Union
Since 2003, Puig holds a seat in the regional Parliament of Catalonia, where he served as spokesman for the ruling coalition Convergence and Union (CiU) until December 2007, while it was the main opposition force. He had previously been a councillor in Parets del Vallès, some 20 kilometers north of Barcelona, and a county councillor in Vallès Oriental, to which this town belongs.
