Renzi, given a mandate by President Giorgio Napolitano to form a new government, pledged to complete electoral reforms by the end of February followed "immediately afterward by labor reforms in March, public-administration reforms in April and fiscal [reforms] in May," ANSA reported.
Renzi, leader of the Democratic Party and mayor of Florence, must conduct talks with other parties on establishing government programs and form a new Cabinet, the report said.
"We intend to work seriously on the Cabinet makeup," Renzi said.
If he is successful in forming a new government, the 39-year-old Renzi will become the youngest Italian prime minister.
Enrico Letta resigned as Italy's prime minister Friday.
