Italian right-wing Italian Interior Minister Matteo Salveni said on Wednesday that the populists in Italy and Poland should spark a "European spring" to replace the center-right in Germany and France.

Salfini, who is also Italy's deputy prime minister, was speaking in Warsaw ahead of his talks with Yaroslav Kaczynski, head of Poland's ruling Nationalist Party.

After his talks with the Polish president, Salvini said he had been offered an agreement between the two countries on a "joint program" for Europe, with the explanation that the program "is not yet in place."

"To overcome differences between parties and differences as a result of geography and cultural customs, we have reached a contract or a charter for Europe, which still does not exist, and I have no ready-made project," Salveni said.

He said he could propose a ten-point pact for Europe in which Italians, Poles, Dutch, Spaniards and Danes "decide whether they support him or not."

He repeated his call for a coalition of "all those who want to save Europe," adding that "the time has come to replace the Franco-German axis with a Polish-Italian axis."

European elections scheduled for late May could lead to the arrival of nationalist and far-right parties from across Europe to the European Parliament, which could disrupt the balance of power now dominated by the center-right.

"Europe has been used to years of talking about the French-German axis, and we are preparing to establish a new balance and new energy in Europe," said the head of the far-right party, Salvini, who met Polish Interior Minister Joachim Brodzinski.

For his part, the Polish prime minister said in an interview with CNBC, the US convergence of positions between Rome and Warsaw, accusing the European Union that "distinguishes" among member states, and said that his government shares Salafini "many" criticisms of the European Union.
