(AGI) Viterbo, Oct 25 - In an interview with news magazinePanorama D'Italia, Lazio's regional president, NicolaZingaretti, said the Democratic Party (PD) convention inFlorence and the union rally in Piazza San Giovanni are twoevents that emphasise the great vitality within the centre-leftPD, even if they are on different sides. "As a member of the PDI feel that the party's life is rather arid. The word 'guest'affected me, since those issuing invitations admit they areinviting someone to a place they consider their home, ratherthan everyone's home," said Zingaretti. . .
