Parliament is bicameral and is located in Rome.
The Chamber of Deputies has 630 members. Three-quarters are elected by popular vote. One-quarter are elected by a system of proportional representation from parties having at least 4% of the total vote. They serve five-year terms. The Senate has 315 members elected to a five-year term in the same way as members of the Chamber of Deputies. In addition, 5 are appointed for life by the president. Also, all former presidents become senators for life. The two houses have equal power in passing laws.
