Italy's referendum explained: What you need to know · CNBC

Italian citizens will vote on constitutional reform on Sunday in what is seen by many analysts as the most significant European political event of 2016. Yes, even bigger than Brexit .


Constitutional reform. Prime Minister Matteo Renzi is campaigning for a "yes" victory in an effort to make it easier to govern the nation moving forwards.

The reforms would remove power from the Senate and mean that proposed laws would only require the approval of the lower house of parliament, as opposed to the current system which requires approval from both houses.

Renzi has even gambled his political future on the referendum having said he would resign if a "yes" vote is rejected.

A "no" vote, as championed by populist party Five Star Movement (5SM), would block the reforms to streamline Italy's public administration and would mean the extensive checks currently required stay in place.

Francesco Oggiano, the author of "Beppo Grillo Parlante", told CNBC on November 14 that he believed 5SM's opposition to the proposed reforms boils down to a new electoral system perceived to be attached to the reforms.

"According to the 5SM, people won't be able to choose their own representatives in the parliament and this is the most important point," Oggiano explained.

"The result (of a 'yes' victory) would be a parliament full of bureaucrats chosen from their parties that, once elected, will just get to satisfy their leader instead of people's needs," he added.

The latest opinion polls, published before a two-week blackout phase of polling in Italy, indicated a 53.5 percent to 46.5 percent in favor of the "no" camp.

Holger Schmieding, chief economist at Berenberg Bank, said in a note on Tuesday he believed the likelihood is that Italy's citizens would reject the reforms.

"Some whispers suggest that more than half of the up to 20 percent of undecided voters may back Renzi in the end," Schmieding said.

"Also, many of the rebellious young people who oppose Renzi may not bother to vote. Whereas the outcome is thus no foregone conclusion, I put the probability of a 'no' vote at 60 percent," he added.

Whatever happens, Adolfo Laurenti, global economist at J. Safra Sarasin, described the post-referendum scenario in a note as "uninspiring".

"While the reform has some intrinsic merits, the domestic debate is centered on the effort to unseat the prime minister. At the same time, financial markets see the vote as a test of the appetite of reform in the country," he concluded.

Analysts from Barclays published a note on Monday to forecast the circumstances in the aftermath of a "yes" or "no" outcome.
