Di Maio, leader of Italy’s anti-establishment Five-Star Movement (M5S), said the ban will be introduced in an attempt to preserve family traditions.
Former Italian prime minister Mario Monti liberalised Sunday trading in 2012 to encourage economic growth during the eurozone crisis.
His decision was slammed by the Roman Catholic Church and unions who argued the country needed to keep its traditional day of rest.
“This liberalisation is in fact destroying Italian families,” Di Maio said on Sunday.
“We need to start limiting opening and closing times again.”
