Sir Keir Starmer’s plan for an international force to support a ceasefire in Ukraine has been dismissed as “a posture and a pose” by Donald Trump’s special envoy.

Steve Witkoff said the idea was based on a “simplistic” notion of the UK prime minister and other European leaders thinking “we have all got to be like Winston Churchill”.

In an interview with pro-Trump journalist Tucker Carlson, Witkoff praised Vladimir Putin, saying he “liked” the Russian president.

“I don’t regard Putin as a bad guy,” he said. “He’s super smart.”
