As well as serving as president from 1999 to 2006, Ciampi was prime minister of a caretaker
government of technocrats from 1993 to 1994. As treasury minister in the late 1990s he played an important role in Italy’s adoption of the euro as its currency.
The news was broken by Italy's current prime minister, Matteo Renzi, who tweeted his government's condolences to Ciampi's widow, and paid tribute to the former head of state:
"A thought of gratitude goes to a man of the institutions, who served Italy with passion", he said.
