“Allies in Europe would start looking at each other and wondering how much they could really trust each other.”
In February, Mr Trump, who could be the US president come January if he defeats the incumbent Joe Biden, described a conversation with a leader of a Nato country about whether the US would protect it if it did not pay two per cent and Russia attacked.

Meanwhile, Labour has doubled down on its support for Nato in an article for The Telegraph by David Lammy, the shadow foreign secretary, and John Healey, the shadow defence secretary.
