Biden’s health and threat of a second Trump term loom over Nato summit

European leaders turn eyes to president as they meet next week and as concerns build for US, their unpredictable ally'

As European leaders and top defense officials from 31 Nato countries descend on Washington next week, all eyes will be focused firmly on Joe Biden, whose faltering performance at last month's debate has added to concerns about the country that some Europeans already described as their unpredictable ally".

The US president has hoped that his leadership at the summit will rescue his campaign against Donald Trump amid concerns about his age and mental acuity. In a primetime interview on US television this week, he said: And who's gonna be able to hold Nato together like me?... We're gonna have, I guess a good way to judge me, is you're gonna have now the Nato conference here in the United States next week. Come listen. See what they say."
