A crunch weekend for talks over the future of Ukraine has been rocked by Donald Trump and Volodymyr Zelensky's White House clash.Sir Keir Starmer will convene a gathering of European leaders at Downing Street on Sunday, aimed at planning for how to police a future Ukraine peace deal.The Prime Minister believes such a deal will have to involve the US.But hopes for unity between European nations and America on Ukraine's future has been shattered by the Friday blowout between Mr Trump and Mr Zelensky in the Oval Office.Plans for the two countries to sign a minerals agreement, which would see continued US military support in exchange for developing Ukraine's natural resources, were also put on hold when Mr Zelensky abruptly left the White House.In an unprecedented series of exchanges in the Oval Office, the US president, his vice president JD Vance and Mr Zelensky all spoke over one another in raised voices.
