“Regardless of the different parties elected and the different majorities in the parliaments, we have always seen that Nato allies have remained committed to the alliance because this is in the security interest of each and every ally,” Stoltenberg said at a meeting of Nato defence ministers in Brussels.

“So I expect France to remain a staunch and important ally also in the future.”

France’s president Emmanuel Macron sent shockwaves across Europe on Sunday by dissolving parliament and calling a snap vote after his liberal party was trounced by the far-right National Rally (RN) at European Union polls.

Macron on Wednesday accused the RN, led by rival Marine Le Pen, of being “ambiguous” about Russia and aiming to “leave Nato”.

Le Pen’s party has previously advocated to leave Nato’s US-led military command structure, but not to quit the alliance as a whole.

More recently, RN leaders have suggested they would not change France’s status in Nato while Russia’s war on Ukraine is ongoing.

French leader Charles de Gaulle previously withdrew France from Nato’s military command in 1966 due to complaints over US domination.

The decision – which saw Nato move its headquarters from Paris to Brussels – was only reversed by former president Nicolas Sarkozy in 2009.
