Christian Popular Union
The UPC was launched in August 2009 by Antonio Satta, a former Christian Democrat who had been the regional leader of UDEUR and, later, of the Sardinian Autonomist Populars. The party is based in Sardinia, but has a national structure, consisting primarily of former members of the UDEUR, notably including Gianfranco Saraca, Luca Bagliani, Danilo Bertoli, Sergio Deorsola, and Antonio Potenza (leader of Basilicata's United Populars).
Massimo Mulas, a regional councillor elected with the Sardinian Democratic Union in the 2009 regional election, joined the party during the legislature. In June 2012, through Mulas, the UPC joined the newly formed parliamentary group Sardinia Tomorrow, along with other centrist councillors.
