Donald Trump is on a fresh collision course with Volodymyr Zelenskyy and European allies after his stunning agreement to buy Russian diesel upended years of US and western pressure on the Kremlin to end its war against Ukraine.

Zelenskyy reacted furiously to Trump’s announcement of the deal with Vladimir Putin on Friday, calling it “absolutely terrible” and “not fair and not honest”.
