A former long-time member of the Christian Democracy party and Member of Parliament since 1976, after the break-up of his party in 1994 Mastella founded a new party, called Centro Cristiano Democratico, together with Pierferdinando Casini. After the victory of Silvio Berlusconi in the 1994 elections, he was successively appointed as Minister of Labour.

In 1998, after the fall of Romano Prodi's first government, Mastella decided to follow Francesco Cossiga, lifetime senator and former Italian Republic President. He left his party to found the Cristiano Democratici per la Repubblica, then Unione Democratici per la Repubblica. This new political party, which supported the new centre-left government led by Massimo D'Alema, lasted only one year however; in 1999, Mastella took over the leadership of UDEUR (then Popular-UDEUR).

Giuseppe Piero Grillo, better known as Beppe Grillo (born 21 July 1948), is an Italian activist, blogger, comedian and actor. He has been involved in politics since 2009 as leader of the Five Star Movement.

Grillo was born in Genoa, Liguria.

After receiving his degree as an accountant, Grillo became a comedian by chance, improvising a monologue in an audition. Two weeks later he was discovered and launched by Italian TV presenter Pippo Baudo. He subsequently participated in the variety show Secondo Voi for two years (1977–78). Later, in 1979, he participated in Luna Park by Enzo Trapani, and Fantastico.

In the 1980s his success rose further, thanks to shows like Te la do io l'America (1982, 4 episodes) and Te lo do io il Brasile (1984, six episodes). In these shows, he narrated his experiences of his visits to the United States and Brazil, with anecdotes and witticisms about the culture, lifestyle and beauty of these places.

As a result, his popularity grew more and more, and he became the protagonist of another show developed especially for him, called Grillometro (Grillometer). In 1986, he was the star of prize-winning advertisements for a brand of yogurt.
