Former Italian Premier Matteo Renzi has urged his Democratic Party to quit its internal squabbling and focus instead on defeating populists during what he dubbed the era of "Trumpism" and protectionism.

Renzi cited U.S. President Donald Trump while making a pitch to other top Democratic figures Monday for a united front with an eye on national elections that might come as soon as the spring.

Renzi said the party, now the biggest in Parliament, should concentrate on countering "Trumpism," or "at least Grillo-ism" on the rise in Italy. He was referring to comic Beppe Grillo, whose anti-euro, populist 5-Star Movement aims to govern Italy.
