President Donald Trump welcomed Ukrainian President Volodymyr Zelenskyy to the White House for a high-stakes meeting as the U.S. president pushed for a deal to end Moscow's war on its neighbor. A host of European leaders joined the pair.

Another major talking point is on security guarantees. Trump says security guarantees for Ukraine would be "provided" by European countries with "coordination" by the US. British Prime Minister Keir Starmer has told the BBC that the UK negotiators will shortly be arriving in Washington for further planning on this.
