But she argued that French leaders’ predictions that Brexit would end in a “nationalist and insular withdrawal” and “a cataclysm for the English” had not come to pass.

“The British got rid of the Brussels bureaucracy, which they could never bear, to move to an ambitious concept of global Britain”, which she pronounced “Brighton”.

“This is not our project. We want to reform the EU from the inside,” she said.

“But the more we free ourselves from the Brussels straight jacket while remaining inside the EU, the more we will turn ourselves to the wider world. It seems to me that’s what the English have well understood.”

Ms Le Pen also pledged to reduce France’s contribution to the EU budget by €5 billion (£4.2 billion) per year.

It currently hovers around €22-25 billion, which puts the country’s net contribution at “between €8-9 billion”.

“I would not stop paying France’s contribution to the EU, I want to diminish it,” she said. “The EU can also make savings in its operating costs.”

Her pledge came a day after Mr Macron, her Europhile rival, argued that her election would lead to a Frexit by stealth and that the election was a “referendum on Europe”.
