Rubio, the Trump administration’s most senior diplomat, said it was “neither our goal nor our wish” to end the transatlantic partnership, adding: “For us Americans, our home may be in the Western Hemisphere, but we will always be a child of Europe.

“And I am here today to leave it clear that America is charting the path for a new century of prosperity, and that once again we want to do it together with you, our cherished allies and our oldest friends.”

However, he repeated several criticisms repeatedly levelled at Europe by the Trump administration, including describing immigration policies as a threat to civilisation, and saying a “climate cult” had taken over economic policy.

On trade, he said Europe and the US had “made mistakes together” by adopting a “dogmatic vision of free and unfettered trade”.

He repeated familiar calls from the US for Europe to invest more in defence, saying: “We want allies who can defend themselves so that no adversary will ever be tempted to test our collective strength.”

In response, von der Leyen said: “[Rubio is] a good friend, a strong ally. And this was, for me, very reassuring to listen to him.”

She continued: “We want a strong Europe. And this is, I think, the message of today.”
