Italy has invited dozens of world leaders to lavish celebrations this week marking the birth of the modern nation 150 years ago, giving new luster to the country's scandal-free president in his largely ceremonial role.
The presidents of Russia, Turkey, Israel, Germany and Argentina are among 80 top officials expected for receptions in the gardens of the Renaissance-era Quirinale presidential palace and a military parade on Via dei Fori Imperiali near the Colosseum. Vice President Joe Biden is representing the United States.
Gül, however, canceled the trip to Italy due to illness.
Foreign Ministry statement said on Wednesday that Davutoğlu is also expected to have talks with his counterparts during the celebrations.
