French President Emmanuel Macron today accused the US of 'breaking free from international rules' and 'gradually turning away' from some of its allies.

Macron delivered his annual speech to French ambassadors at the Elysée Palace, amid a major struggle among the continent's leaders to come up with a co-ordinated response to US assertive foreign policy in the Western hemisphere. 

In the last few days, Donald Trump launched an unprecedented incursion into Venezuela to capture its leader, Nicolas Maduro, and renewed threats to annex Greenland, which is part of EU member Denmark.

Sir Keir Starmer has also weighed in on the Greenland row, reiterating his position on the territory in a call with Denmark's Prime Minister, Mette Frederiksen.

Downing Street said the pair agreed on the importance of deterring Russian aggression in the High North and that Nato should step up efforts in the region to protect Euro-Atlantic interests.

'The United States is an established power, but one that is gradually turning away from some of its allies and breaking free from international rules that it was still promoting recently,' Macron told ambassadors at the Elysée Palace.

'Multilateral institutions are functioning less and less effectively,' Macron added. 'We are living in a world of great powers with a real temptation to divide up the world.'

Macron's impassioned speech came just a day after Trump mocked his accent at a meeting of Republican leaders.

Trump recounted how he made France agree to tripling its drug prices by threatening to increase tariffs on all French imports to the US. 

Mocking the French leader's accent, he said Macron told him: 'Donalddd, you have a deal. I would like to increase my prescription drug prices by 200 per cent or whatever. Whatever you want, Donald, please don't tell the population, I beg you'.

He claimed to have told France to either agree to the US's demands or face a massive 25 per cent tariff on all French products, including champagne and wine.

Downing Street later said that Sir Keir Starmer had raised the issue of Greenland directly in a call with Denmark's Prime Minister, Mette Frederiksen.
