Marine Le Pen’s party has pledged to boost spending power, slash immigration and restore law and order

The far-right National Rally (RN) has strengthened in final polls, including one suggesting it could be on course for a historic parliamentary majority, as candidates fought for votes on the last day of campaigning before the first-round ballot in France’s most momentous election for decades.

Two days before Sunday’s ballot, two polls on Friday showed Marine Le Pen’s anti-immigration, France-first party pulling steadily further ahead in a race it has led since President Emmanuel Macron called the shock ballot almost three weeks ago after the defeat of his centrists in the European parliamentary election.
