An anti-establishment candidate in Rome has comfortably clinched a runoff mayoral election slot, as Romans disgusted by corruption scandals and deteriorating city services largely turned away from traditional left and right parties which governed the Italian capital for decades.

Virginia Raggi of the 5-Star Movement took 35.3 percent of the vote Sunday in Rome, trailed by Premier Matteo Renzi's Democratic Party candidate Roberto Giachetti, with just under 25 percent. Since no candidate took more than 50 percent in balloting, the top two will face a runoff on June 19.

Renzi's candidate for Milan, Giuseppe Sala, widely praised for smooth management of that city's Expo 2015, finished barely ahead of the center right-candidate, Stefano Parisi, and both head to a runoff.

Renzi said Monday: "We aren't happy" with the overall results.
