Marine Le Pen is spoiling for a fight. The leader of France's Front National vows to smash the existing order of Europe and force the break-up of monetary union, if she wins the next election.

It is no longer an implausible prospect. "We cannot be seduced," she said, brimming with confidence after her party secured 46pc of the vote in a by-election earthquake a week ago. Her candidate trounced the ruling Socialists in their own bastion of Villeneuve-sur-Lot.

"The euro ceases to exist the moment that France leaves, and that is our incredible strength. What are they going to do, send in tanks?" she told the Daily Telegraph at the Front National's headquarters, an unmarked building tucked away in the Paris suburb of Nanterre. Her office is small and workaday, almost austere.

"Europe is just a great bluff. One side there is the immense power of sovereign peoples, and on the other side are a few technocrats," she said.

For the first time, the Front National is running level with the two governing parties of post-War France, Socialists and Gaullistes. All are near 21pc in national polls, though the Front alone has the wind in its sails.
