Giovanni "Gianni" Alemanno (born 3 March 1958) is an Italian politician who from April 2008 until June 2013 was mayor of Rome for The People of Freedom.

The first arrest took place in Rome on 20 November 1981, when he was accused (along with four others) of intimidating a 23-year-old student, Dario D'Andrea, who was hit on the head by Sergio Mariani, then secretary of the Fronte della Gioventù (the youth organization of the Italian Social Movement).

In 1995 he joined the newly formed National Alliance party, which succeeded the Italian Social Movement following its repudiation of extremism at the Congress of Fiuggi in the 1994.

Alemanno rejected a formal alliance with the far-right party, but his critics emphasized that his victory was greeted by crowds of supporters, among them far right skinheads, who chanted "Duce!

[3] Alemanno said that the attack was an isolated case, and repeated that he wanted to crack down on crime, regaining total control of the territory.

[9] Other important measures of the Alemanno Administration were: an ordinance against prostitution in the streets,[10] an attempt to recapitalize the municipal company AMA redefining its role,[11] the census and the dismantling of six camps for nomads [12] (including the Casilino 900) setting up garrisons, thus ensuring immunizations and education for Romani children, and to expel illegal immigrants.

In 2004 to encourage and patronage the Italian Mountaineering Expedition and Delegates bound for K2 he arrived Pakistan for participation in celebration of K2 Golden Jubilee ceremony at Concordia base camp.

On 23 March 2015 he was indicted along with seven other people due to an alleged illicit funding received for the Lazio regional elections of the 2010 that would have been masked by a false poll in favor of Renata Polverini's list.

Alemanno says: "I have never called for or received unlawful financing, this is a marginal event I could not verify the legal requirements because it was not about my election campaign."
