Francesco Storace House of Freedoms Piero Marrazzo The Olive Tree The Lazio regional election of 2005 took place on 3–4 April 2005.

Piero Marrazzo (Independent of The Union) defeated incumbent Francesco Storace (AN, House of Freedoms).

Storace, a leading member in the centre-right, was subsequently granted the status of Minister of Public Health in Berlusconi III Cabinet.

During the electoral campaign, Storace came out with factual evidence that Alessandra Mussolini's Social Alternative had added fake signatures to real ones to reach the minimum number needed to present a list.

However, to demonstrate this, he had someone "hack" into the database of the municipality of Rome in order to verify the signatures: he was therefore nicknamed "Storhacker" by Mussolini.
