Jordan Bardella, leader of France's National Rally and the frontrunner in presidential polls for 2027, vowed on Friday to win the French elections and mark a shift in the course of the European Union.

Bardella said this on the second day of his two day visit to Poland where he met with right-wing and nationalist leaders ahead of his country's presidential elections next year.

His visit to Poland also comes as Poland is preparing for its own parliamentary elections, set to take place next autumn.

"I am convinced that over the course of the year 2027, if our two movements achieve electoral victories, we will have the opportunity -- because France and Poland are two major powers in Europe -- to redirect the way the European Union operates, as I often say, to change everything without destroying anything." Bardella said.

He added that he would like to "put the Commission and the EU back at the service of the nations and no longer the other way around".
