Italians who are living abroad for three months or more can vote in five referendums on the justice system being held in June, the foreign ministry tweeted on Tuesday.
"Are you an elector who is temporarily abroad for at least three months and want to vote?" read the tweet.
"Let your municipality know this by 11 May," the tweet added.
Italian electors abroad will be able to vote by postal ballot on the referendums taking place on 12 June. The plebiscites include one on abolishing a law stopping individuals convicted of serious crimes including corruption, from standing in European, national and regional elections for six years.
Another referendum is about separating the careers of prosecutors and judges, while others concern judicial remand, elections to the judiciary's self-governing body (CSM), and allowing lawyers to vote on the performance of magistrates.
