Mussolini, who had been a member of the National Alliance (AN) since its foundation, suddenly left that party on 28 November 2003, following the visit of party leader and the Deputy Prime Minister Gianfranco Fini to Israel, where he described fascism as "the absolute evil" as he apologised for Italy's role as an Axis Power during the Second World War.
That was a surprising move, as Mussolini, during her political career, had always taken social progressive stances on many issues, including abortion,[3] artificial insemination,[4][5] gay rights[6][7][8] and civil unions.
Mussolini herself re-approached with Fini and was preparing her re-entry in AN when Silvio Berlusconi launched The People of Freedom (PdL).
In October 2012, the balance of accounts of the People of Freedom showed that Social Action had received €100,000 of financial support from the PdL.
[15] Within the PdL Mussolini soon became the leader of the "pro-immigrant" wing of the party, often opposing some of the policies of the Berlusconi government or taking an independent line from it.
