The new lawmaker is now a member of the biggest nationalist bloc in the EU parliament, which brings together parties determined to take back power from the elite in Brussels.
Mr Bardella is a vocal eurosceptic and vice-president of the Marine Le Pen’s Rassemblement national (RN) party.
Speaking yesterday he told France Info radio: “The European Union, today, embodies collective powerlessness, because we are unable to engage in dialogue with anyone.”
The far-right politician led the RN to victory in last month’s elections to the European Parliament, nudging President Emmanuel Macron’s pro-EU La République en Marche (LREM) party into second place.
Mrs Le Pen’s RN won 23.3 percent of the French vote, while the centrist LREM alliance won 22.4 percent.
The far-right’s victory dealt a symbolic blow to Mr Macron, who has put European renewal at the heart of his presidency and personally invested time in the campaign. But it has galvanised Mrs Le Pen, who for her part framed the president’s defeat as a repudiation by voters of his business-friendly policies and pro-EU, liberal vision.
Mrs Le Pen’s win was mirrored across Europe, namely in Italy, Germany and Britain, where populist, eurosceptic parties made significant gains.
Last week, the French nationalist unveiled a new far-right group in the EU parliament, uniting eurosceptics from across the bloc determined to seize back sovereignty from Brussels and regain control of their national borders.
The new Identity and Democracy (ID) alliance brings together Mrs Le Pen’s RN, Italian Deputy Premier Matteo Salvini’s League Party and Germany’s Alternative for Germany (AfD), among others.
The ID group holds 73 of 751 seats and is the fifth-biggest bloc in the newly elected assembly, right behind the greens.
Mr Bardella, who is expected to have a loud voice in ID, also commented on US President Donald Trump’s 2020 re-election bid, praising his “America First” policies, which in recent years have sparked both shock and awe.
France should “draw more inspiration” from Mr Trump’s “protectionist policies,” Mr Bardella said, adding that the US leader had successfully put “American interests” first.
“When Donald Trump was elected, we were told that it would be an economic disaster. But I note today that his economic record is very good. He has created so many jobs that there is now a labour surplus,” he continued.
“He has restored a form of pride in America. All superpowers today … the US, Russia, Japan, are successful because they are nations that are proud of themselves,” Mr Bardella added, pointedly omitting the EU.
But while Mr Trump’s hardline protectionism is often lauded by Europe’s sovereignists, many in Brussels are unhappy with Washington’s sharp turn inwards.
Since taking power in January 2017, he has quit the Paris climate agreement, taken the US out of the landmark nuclear accord with Iran and sparked a string of trade wars with the EU, China, Mexico and Canada, disrupting the world order.
