In 2006, his name was frequently suggested for the office of President of the Italian Republic. Napolitano was the second person proposed by the centre-left majority coalition,
The Union, in place of
Massimo D'Alema, after the chance of a joint vote on D'Alema had been rejected by leaders of the centre-right coalition
The House of Freedoms. Even though Napolitano appeared at first a candidate the House of Freedoms could converge on, the proposal was rejected much like that of D'Alema.
The centre-left majority coalition, on
May 7 2006, officially endorsed Giorgio Napolitano as its candidate in the
special election that began on May 8. The
Vatican endorsed him as President through its official newspaper,
L'Osservatore Romano, just after the Union named him as its candidate, as did
Marco Follini, former secretary of the
UDC, the right-leaning Christian party, member of the House of Freedoms.
Napolitano was elected on May 10, in the fourth round of voting—the first round which required only an absolute majority, unlike the former three which required two-thirds of the votes—with 543 votes (out of a possible 1009). He was the first former Communist to become President of Italy, as well as the third Neapolitan after
Enrico De Nicola and
Giovanni Leone. After his election, expressions of esteem toward his person and his authority as future
President of the Italian Republic were made by both members of the Union and of the House of Freedoms (who had issued a
blank vote), such as
Pier Ferdinando Casini. Nevertheless, some Italian right-wing newspapers, such as
il Giornale, expressed concerns about his communist past. He started his term on May 15.
On
July 9, 2006, Napolitano was present at the
FIFA World Cup final, in which the Italian team defeated France and won its fourth World Cup, and afterwards he joined the players' celebrations. He is the second President of the Italian Republic to be present at a triumphal World Cup final, after
Sandro Pertini.
On
September 26, 2006, Napolitano made an official visit to
Budapest, Hungary, where he paid tribute to the fallen in the
1956 revolution, which he initially opposed as member of the Italian Communist Party, by laying a wreath at Imre Nagy's grave.
On
February 10, 2007 a
diplomatic crisis arose between Italy and
Croatia, after President Napolitano publicly condemned the
foibe massacres on the Foibe Memory Day. The European Commission did not comment on this event, but did comment (and partly condemn) the response by Croatian president
Stjepan Mesić, who described Napolitano's statement as racist, because Napolitano did not refer either to Slovenians or Croatians as a nation, when he spoke about a "
Slavic annexationist aspiration"" for the
Julian March (at the time, Slovenians and Croatians fought together in the
Yugoslav Resistance Movement). Another matter of debate in Croatia was that the Italian President made awards to relatives of 25 foibe victims, who included the last fascist Italian
prefect in
Zadar, Vincenzo Serrentino, convicted to death in 1947 in
Šibenik. That was seen by Mesić as "historic revisionism" and open support for
revanchism. President Napolitano's remarks on the foibe massacres were praised by both centre-left and centre-right in Italy, and both coalitions condemned Mesić's statements, while the whole of Croatia stood by Mesić, who later acknowledged that Napolitano didn't want to put in discussion the
Peace Treaty of 1947.
On
February 21, 2007, Prime Minister Romano Prodi submitted his resignation after losing a foreign policy vote in the
Parliament; Napolitano held talks with the political groups in parliament, and on
February 24 rejected the resignation, prompting Prodi to ask for a new
vote of confidence. Prodi won the vote in the upper house on
February 28 and in the lower house on
2 March, allowing his cabinet to remain in office.
